Anritsu ML2430A operation manual Offfix A,-47DB, Offtbl

GPIB OPERATION ML24XXA NATIVE COMMANDS

OFFFIX Offset fixed value SENSOR

Syntax: OFFFIX <s>,<val>[units]

s:A or B

val: –99.999 to +99.999 units: dB

Remarks: The value added to the sensor if the offset type is set to FIXED.

Example: To set the fixed offset for sensor A to -47 dBm:

OFFFIX A,-47DB

Query: OFFFIX? <s>

Returned

String: OFFFIX <s>,<val>

OFFTBL Specify the table used to apply offsets to the sensor SENSOR

Syntax: OFFTBL <s>, <val>

s:A or B val: 1 to 5

Remarks: If the Offset Type is set to TABLE, use this command to specify which of the five offset tables to apply to the sensor.

The tables are a set of frequency-against-dB offsets. The offset value used from the table depends on the setting of the frequency correction source. If the source is FREQUENCY, the entered frequency is used to calculate the offset from the table. If the frequency correction source is V/GHz, the fre- quency value calculated from the supplied ramp input is used to calculate the offset from the table.

If the frequency does not match any frequency in the table, interpolation is used to calculate the correct offset.

NOTE

If the frequency is greater than the maximum frequency in the table, the offset value from the maximum table fre- quency is used. If the frequency is less than the minimum frequency in the table, the offset from the minimum table frequency is used. The frequency comparisons start from the beginning of the table; if the entry is 0 Hz, this is counted as the end of the table.

Query: OFFTBL? <s>
