TALK
This indicator is on when the instrument is in the talker active state. Place the unit in the
talk state by addressing it to talk with the correct MTA (My Talk Address) command.
TALK is off when the unit is in the talker idle state. Place the unit in the talker idle state by
sending an UNT (Untalk) command, addressing it to listen, or sending the IFC (Interface
Clear) command.
LSTN
This indicator is on when the Model 2790 is in the listener active state, which is activated
by addressing the instrument to listen with the correct MLA (My Listen Address) com-
mand. LSTN is off when the unit is in the listener idle state. Place the unit in the listener
idle state by sending UNL (Unlisten), addressing it to talk, or sending IFC (Interface
Clear) command over the bus.
SRQ
You can program the instrument to generate a service request (SRQ) when one or more
errors or conditions occur. When this indicator is on, a service request has been generated.
This indicator stays on until the serial poll byte is read or all the conditions that caused
SRQ have been cleared. See
LOCAL key
The LOCAL key cancels the remote state and restores local operation of the instrument.
Pressing the LOCAL key also turns off the REM indicator and returns the display to nor-
mal if a user-defined message was displayed.
If the LLO (Local Lockout) command is in effect, the LOCAL key is also inoperative.
Programming syntax
The information in this section covers syntax for both common commands and SCPI com-
mands. For information not covered here, see the IEEE-488.2 and SCPI standards. See
Section 12
Command words
Program messages are made up of one or more command words.
Model 2790 SourceMeter
If LLO is in effect, LOCAL will be locked out. If TRIGger:SOURce is set to man-
ual, the TRIG key will be active in remote.
