It has come to my attention that there is alot of intrest in exploiting the screen capture ability of the HP-8920 series of service monitors, therefore I shall make things simple.
Login to Yahoo Groups and download the BTS Laptop Software: http://groups.yahoo.com/group/Repeater-Builder/files/FluX%20Research/HP-8924C/E6385A_BTS_SW.zip Build Cable for 'Serial port 9' as described on page 248 of the Users Manual: http://cp.literature.agilent.com/litweb/pdf/08924-90038.pdf Set Serial Port Settings on the I/O Configure Screen (TO SCREEN > MORE > I/O CONFIG) in service monitor to: Serial In: Inst IBASIC Echo: On Inst Echo: On Baud: 19200 Parity: N Data length: 8 Stop length: 1 Rcv Pace: None Xmt Pace: None Set Printer to 'Serial' in the Print Configure Screen (SHIFT PRINT) With service monitor connected to laptop runing the software press (PRINT) to initaiate a capture. To answer some questions: > What is the spectrum analyzer sesitivity in uv? hmmm. It will generate down to -137dBm but I am not sure what the sensitivity is on receive. I will tell you I can use the Antenna input port to regularly pick up WWV on 10MHz using a 2 ft long telescoping whip antenna in Arizona. As for the spec analyzer, the noise floor changes depending on the sweep span. at a 100kHz sweep it looks like -115dB, With a 1GHz sweep it is more like -80. The spectrum analyzer also has a non calibrated high sensitivty mode that will get you about another 10dB of sensitivity. I understand they are more sensitive then the comparable IFR-1600S. you can run the service monitor in uV or dBm, I run dBm so I am unsure without looking at a chart what that translates to. > And also what is Option H14? You must be looking at Ebay. Option H14 means that it was back to HP for calibration at least once in it's life. > and what is the Frequency range of the unit from .000MHz to 0000000MHz, Depends on the version. The RF port will be rated to 30MHz to 1000MHz with the electronic input module or 400kHz to 1000MHz with the standard relay input module. The name plate above the screen will denote which range it is. The range on the spectrum analyzer is 0 Hz to 1050MHz.
