LOCAL (For serial port remote control only)
Puts the 5790A into the local state. This command duplicates the IEEE-488 GTL (Go To
Local) message.
Parameter
None
LOCKOUT (For serial port remote control only)
Puts the 5790A into the local with lockout state. This command duplicates the IEEE-488
LLO (Local Lockout) message.
Parameter
None
MEAS?
Trigger (or in continuous trigger, restart trigger) a new measurement, wait for it to
complete, then retrieve the value of the present input measurement (the most recently
completed input measurement). If a timeout argument is given and no settled
measurement occurs within the timeout period, the command generates an error and
presents the closest approximation of the measurement obtained in the timeout period.
The MEAS? command is equivalent to the following sequence of commands: TRIG;
*WAI; VAL?
Parameter
\<timeout in seconds\> (optional)
Response
1. (Float) The magnitude of the measurement in volts.
2. (Float) The frequency of the measurement in Hertz.
3. (Integer) A code describing the measurement as follows. If more than one conditions
is true, the highest number only is returned.
•
0 = Measurement conditions valid, no other condition below is true
•
1 = Frequency underrange
•
2 = Frequency overrange
•
3 = Measurement settled, but digital filter not full
•
4 = Measurement is unsettled ("U" annunciator is lit)
•
5 = Value is underrange ("LLLLLLLL" on display)
•
6 = Value is overrange ("HHHHHHHH" on display)
•
7 = Value is invalid ("--------" on display)
MODE?
Returns the current operating mode. See the response below for modes.
