Advantest R3131: Cannot set marker frq via GPIB/serial?

[Yansi]

Am I dumb or did they really forgot to add a command to set the marker frequency? It is possible to freely move the marker using the front panel, but hell I can't find any command to position the marker using GPIB/serial port.

I see only the MF? which returns the frequency marker is at, but there is none comand I can set it remotly.

Sending MF followed by a frequency does nothing.

Thanks for any hints how to do it.

It depends on what you want to do.
Find the peak? Easily.
Sending a PS command.
Read the frequency of MF? .
We read the level of ML? .

[Yansi]

Finding peak is great and what not, but if I want to get the RF level at an exact frequency of interest, that for example, is not a peak? I should then try reading out the whole sample memory? 

[serg-el]

Easily.
Page 4-34.
To measure the level at a frequency of 30 MHz.
Give the command MK30MZ
Give the command ML? . RTFM

Ah great.

They forgot to include the "MK" command in Table 4-8. Fuuuuuuuck.

"MK 405.2E6" happily moves the marker to 405.2 MHz.

Thanks for the hint!

Maybe because the MK command in table 4-7?   

[Yansi]

Well, whatever. Those tables are just mess, not  a good description of commands.

All is well now. Automated measurement done and working great, easing me a LOT of manual labor sifting through whole cartons of devices to test
