GPIB 488.1 Old Giga-Tronics GT 1026 Signal Generator with only Low-Level Commands

[s_koehler]

Hello,

i'm trying to send proper commands the some old GIGA-TRONICS GT 1026 Signal Generator. My problem is kind of similar of that in another post : Link

Here a is a list of my knowledge so far:

-device only supports IEEE 488.1 standard (1978)
-"low-level" commands like ibrd, ibcmd, etc. work well in "Interactive Control"
-device lists up when scanning for instruments
-device sets into REMOTE state when connecting through "Communicate with instrument"
-device can be set to LOCAL via: ibcmd "\x01"
-device can be adressed as listener via: ibcmd "?&@" &=MLA6 @=MTA0
-no command send via ibwrt or the write function in the "Communicate with instrument" panel works
-when reading out data device always responses: F07RSY1 MOD: NO STA RECEIVED
-the known commands to control the device are the same like in the mentioned post above, e.g. "GEN FIXED; FA 12.3E+3"
-using GPIB-USB-HS adapter with NI-488.2 2.73 and MAE 4.6.2

What am I doing wrong?

With kind regards,

Did you read the part in the other thread about configuration switch inside the unit? Does it apply to this one?

[s_koehler]

Yes, I read that part. In this specific manual there are some differences:

1.3 Syntax Configuration

The standard remote control syntax (as described in this manual) is enabled by setting S7 on the CPU PC board (A2) to the on(up) position.
S7's off position might be required in unusual applications.
The instrument is normally shipped from the factory with S7 set to the on position.

Nothing is mentioned about that 'CIIL' syntax. And I don't know what a "unusual" application might be. Perhaps i get the opportunity to open the case and check for the board setting.
