As you know,I got a project that need to control Marconi Instrument-Radio conmunication test set 2955B by computer,I download its 《Programmer Guide》 from here.but soon I got another problem:It seems that 2955B do not have any GPIB command to turn off its RF output in RX TEST mod,you can set RF Modulation off/on by GPIB command but not RF OUTPUT.
I also try to change its TEST MOD from RX TEST to TX TEST,but It seems no good enough to my project,there is a "ON/OFF" key on 2955B' s front panel,and you can turn off/on its RF OUTPUT by press "IN/OFF"key manually,In my opinion,if you can do something manually,you also can do the samething by GPIB commands.is that right?
I have sent an E-Mail to Marconi many weeks ago,but nothing back,so may be somebody here can help me about this problem,thank you!
