GPIB Operation ML24xxA Native Commands
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 8-39
FROFF (Frequency/Offset Display)
FRST (Factory Reset)
GMNMX (Return the minimum and maximum values)
Syntax: FROFF <state>
state:
ON or OFF
Remarks: This command turns on the top line information text displaying the
frequency and offset for the sensors used, similar to the min-max data
display except the left hand data is for sensor A and the right hand is for
sensor B. This command is only valid if the sensor cal factor source is set
to either frequency or V/GHz, and the sensor is used in a displayed
channel.
The display is 'FQ nn.nnGHZ OS nnn.nnn' for each sensor.
The frequency (FQ) is the entered frequency if the cal factor source is set
to frequency, or the calculated frequency if the cal factor source is
V/GHz.
The offset (OS) is the fixed offset if set to fixed, or the offset table
interpolated offset value depending on the frequency if the offset for the
sensor is set to table. If the offset for that sensor is OFF, dashes are
displayed in the OS part of the top line data.
Query: FROFF?
Returned String: FROFF <state>
Syntax: FRST
Remarks: Resets the ML243xA to the factory default configuration (see Appendix
A). Unlike the *RST command, the offset tables are cleared and all
external interfaces are reset. Note that any settings in the *ESE and
*SRE registers prior to this command will be reset. The equivalent front
panel key sequence is System > Setup > PRESET > FACTORY.
Syntax: GMNMX <c>
c: 1 or 2
Remarks: When min/max tracking is turned on, this command is used to read the
values. The format returned is:
<min_value>,<max_value>
