manual provides general information, installation, and operating information for the anritsu PSN50 calxpert ? software application for the PSN50 usb power se nsor and is intended for users who want to calibrate the PSN50 usb power sensor themselves or through a third-party calibration laboratory. the procedures described in this manual are specific to the PSN50. throughout th is manual, the terms PSN50 and power sensor will be used interchangeably to refer to the device. manual organiza tion is shown in the table of contents. this chapter contains a description of the PSN50 po wer sensor and a brief background on power sensor calibration. 1-2 description the PSN50 power sensor is a highly accurate, instrument that comm unicates with anritsu handheld (portable) instruments. the power measurement capability of the PSN50 is intended to mimic that of a traditional thermal (thermo-electric) power sensor; theref ore, it is ideal for meas uring the average power of cw, modulated rf waveforms such as 3g, 4g, ofdm, and multi-tone signals. in ot her words, it measures true rms power regardless of the type of input signal. the PSN50 sensor is a dual path diode sensor where ea ch detection path is assign ed to measure a specific range of input power levels. the high power path is a ssigned to measure power from +20 dbm to ?7 dbm while the low power path is assigned to measure power from -7 dbm to ?30 dbm. within th eir assigned power levels, each of the detection diodes are oper ating in square-law and are inherently linear in power without requiring any sophisticated correction. an additional benefit of being inherently linear with the absence of complex corrections allows the PSN50 to be linear with virtually any signal type including cw and complex modulated signals such as wcdma or wimax. note the power sensor has a usb 2.0 interface with a usb type mini-b port. the PSN50 can be remotely programmed over this usb interface. in addition to programming, the PSN50 is powered by the usb. the interface is usb 2.0 compatible, but with an interface speed of 12 mbps. figure 1-1. PSN50 block diagram high power path low power path free datasheet http:// 1-3 power sensor calibration background chapter 1 ? general information 1-2 pn: 10585-00022 rev. b PSN50 calxpert sug 1-3 power sensor calibration background in general, the following items are needed to calibrate any modern power sensor: ? sensitivity calibration (50 mhz) ? calibration factor (calfactor) characterization ? linearity characterization ? temperature characterization ? range ?connection? characterization sensitivity calibration and calfactor ch aracterization are performed at a 0 dbm power level. they are strictly a calibration of the high power detection path. sensitivity calibrates the sensor?s response at 0 dbm and 50 mhz. calfactor test calibrates the sensor?s frequency response with respect to 50 mhz and 1 mw. the PSN50 eeprom contains very pr ecise linearity and temperature characterization data that are beyond the means of most third-party calibrat ion labs. linearity means the sensor?s response as it relates to input power. each one of the detection diodes (high and low po wer paths) operates in square-law and is inherently linear in power; therefore, they do no t require periodic linearity calibration. the temperature characteristics of the detection elem ents do not change with normal aging and wear; therefore, temperature calibrat ion is not needed for routine calibration. if a sensor is damage due to excessive power or some other physical damages, then the power sens or needs to be returned to the factory for repair and calibration. contact your local anritsu service center an d return the sensor with a detailed description of the observed problem(s). the range connection characterization is performed at a transitional power (?7 dbm) between the high and low power detection paths. this test calibrates the lo w power detection path to th e high power detection path so that the two elements combine for a wide dynami c power range (+20 dbm to ?3 0 dbm) while maintaining a seamless linear response. note calfactor tests are performed at countless calib ration laboratories in the industry; and each laboratory has its own techniques, equipment, and measurement uncertainties. choosing the calibration laboratory will depend on the applicat ion and uncertainty requ irements. it is highly recommended that customer choose a high quality la b that has experience in performing power sensor calibrations. anritsu will leave the user to de cide which calfactor calib ration service to use. otherwise, sensors can be sent to anritsu for periodic calibrations. free datasheet http:// PSN50 calxpert sug pn: 10585-00022 rev. b 2-1 chapter 2 ? installation (pc only) 2-1 introduction this chapter provides information on installing the PSN50 calxpert ? application and power sensor drivers. it contains the following: ? hardware and software requirements ? installing the PSN50 calxpert application ? installing the PSN50 power sensor drivers 2-2 hardware and software requirements please make sure that th e following minimum requirements are met for installing and using the software: ? intel ? pentium ? iii with 1 gb ram or intel ? pentium ? iv with 512 mb ram, or equivalent (intel ? pentium ? iv with 1 gb ram recommended) ? microsoft ? windows vista ?

connector care and handling anritsu ma241x8a power sensors are high-quality prec ision laboratory instrument s and should receive the same care and respect afforded to su ch instruments. follow the precauti ons listed below when handling or connecting these devices. complying with these precautions will guaran tee longer component life and less equipment down time due to connector or device failure. also, such co mpliance will ensure that power sensor failures are not due to misuse or abuse ? two fa ilure modes not covered un der the anritsu warranty. beware of destructive pin depth mating connectors destructive pin depth of mating connect ors is the major cause of failure in the field. when an rf component is mated with a connector having a de structive pin depth, damage will us ually occur to the rf component connector. a destructive pin depth is one that is too lo ng with respect to the reference plane of the connector ( figure a-1 , left). the pin depth of dut connectors should be measured to assure compatibility before attempting to mate them with power sensor connectors. an anritsu pin depth gauge or equivalent can be used for this purpose ( figure a-1 , right) if the measured connector is out of tolerance in the ?+? region, the center pin is too long (see table a-1 , below). mating under this condition will likely damage the pr ecision rf component connec tor. if the test device connector measures out of tole rance in the ??? region , the center pin is too short. this should not cause damage, but it could result in a poor connection an d a consequent degradation in performance. figure a-1. pin depth table a-1. allowable dut connector pin depth connector type pin depth gage model # pin depth (inches) pin depth gage readout n-male sc3825 0.207 +0.030 ?0.000 0.207 +0.000 ?0.030 n-female sc3825 0.207 +0.000 ?0.030 0.207 +0.000 ?0.030 0 1 2 3 4 5 1 2 3 4 2 11 2 reference plane female pin depth (inches) male reference plane pin depth (inches) free datasheet http:// appendix a ? connector care and handling a-2 pn: 10585-00022 rev. b PSN50 calxpert sug avoid over torquing connectors over torquing connectors is destru ctive; it may damage the connector center pin. always use a connector torque wrench when tighteni ng connectors. never use pliers to tighten connectors. avoid mechanical shock connectors are designed to withstand years of normal be nch handling. however, do no t drop or otherwise treat them roughly. mechanical shock will si gnificantly reduce their service life. avoid applying excessive power the PSN50 sensor is rated at 150 w maximum continuo us input power given a load vswr of 3:1 or less. exceeding the maximum input power level may permanently damage the in ternal components, rendering the power sensor useless. cleaning connectors the precise geometry that makes the rf component's high performance possible can easily be disturbed by dirt and other contamination adhering to th e connector interfaces. when not in use, keep the connectors covered. to clean the connector interfaces, us e a clean cotton swab that has been dampened with denatured alcohol. the following are some important tips on connector care: ? use only isopropyl alcohol as a cleaning solvent. do not use excessive amounts of alcohol as prolonged drying of the connector may be required. ? never put lateral pressure on th e center pin of the connector. ? verify that no cotton or other foreign mate rial remains in the co nnector after cleaning. ? if available, use compressed air to remove foreign particles and to dry the connector. ? after cleaning, verify th at the center pin has no t been bent or damaged. ? avoid touching connector mating planes with bare hands. natural skin oi ls and microscopic dirt particles are very hard to remove. ? always check the pin depth of dut co nnectors before use to determine if they are out of spec. one bad connector can damage many. ?

serial port compatibility the PSN50 calxpert application requires that the serial ports from com1 to com16 be used. you can find out the com port number by going to start | settings | control panel | sy stem | hardware | device manager | ports (com & lpt) . disconnect and reconnect the power sensor?s usb cable from the comp uter and notice the new com port number that appears in the ports list. if the com port number is less than 16, then the pc application is ab le to communicate with the sensor. however, in some cases when the po wer sensor is connected, windows ma y map the serial port to a port number greater than 16, such as com17 or com29 depe nding on which usb port that is being used. if the power sensor is connected and the PSN50 calxpert applic ation does not connect to the sensor, a port number above com16 may be assigned to the sensor. to correct th is problem, follow one of the methods outlined in the following sections. figure b-1. device manager free datasheet http:// b-1 method 1?download updated software appendix b ? serial port compatibility b-2 pn: 10585-00022 rev. b PSN50 calxpert sug b-1 method 1?download updated software the preferred method for resolving seri al port compatibility issues is to download software updates for your product from www.us.anritsu.com . b-2 method 2?trying a different usb port 1. disconnect the usb end of your power sensor from your computer. 2. connect the usb power sensor to a different usb port on your computer. connecting to a usb hub tends to increase the port numbers, so conn ecting directly to the computer?s usb port usually provides the best result. 3. open the device manager to see if th e new port assignment is from com1 to com16. if it is not, return to step 1 and connect to a different usb port. if the port assignment is fr om com1 to com16, the problem has been resolved and no further action is required. b-3 method 3?remapping a serial port a serial port may be remapped to a different number, such as changing a serial port from com19 to com5. this may be needed if method 1 above does not result in a serial port a ssignment from com1 to com16 or if you prefer to use a usb hub or a specific usb port on your computer. 1. open the system properties by going to start | settings | control panel | system , or simultaneously pressing the windows and pause keys. free datasheet http:// appendix b ?
