GPIB OPERATION

ML24XXA NATIVE COMMANDS

FROFF

Frequency/Offset Display

SYSTEM

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 chan- nel.

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 interpo- lated 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?

FRST

Factory Reset

SYSTEM

Syntax: FRST

Remarks: Resets the ML2430A Series to the factory default configuration (see Ap- pendix 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 SystemSetupPRESETFACTORY.

GMNMX Return the minimum and maximum values

DATA OUTPUT

Syntax: GMNMX <c>

c:1 or 2

Remarks: When min/max tracking is turned on, this command is used to read the val- ues. The format returned is:

<min_value>,<max_value>
