MEM:UNIT
Syntax:
MEMory[:TABLe]:UNITspace<choice of units dBm or Watt>
Example:
OUTPUT @PWR_MTR;MEM:UNIT DBM ! SETS ANALOG OUT POWER UNIT
Description:
This command selects between one of two configurations, log units or linear units. In either
case the voltage output will be numerically linear. Be sure to set the units control properly
(dBm or W) before trying to set the numeric values.
Syntax:
MEMory[:TABLe]:UNIT?
Example:
OUTPUT @PWR_MTR;MEM:UNIT? ! QUERIES ANALOG OUT POWER UNIT
Description:
This query reports the units used for analog output configuration.
MEM:POWer
Syntax:
MEMory[:TABLe]:POWerspace<start value from -80 to +20 dBm>comma<stop value from -80 to +20 dBm>
Example:
OUTPUT @PWR_MTR;MEM:POW -70,20 ! SETS ANALOG OUT POWER RANGE (IN DBM)
! FROM -70 TO 20 DBM
Description:
If log units are selected for analog output control, this command selects the beginning and
end points of the power levels which will be assigned corresponding voltages at the analog
output.
Syntax:
MEMory[:TABLe]:POWerspace<start value from 0 to 0.01 W>comma<stop value from 0 to 0.01 W>
Example:
OUTPUT @PWR_MTR;MEM:POW 0,1E2 ! SETS ANALOG OUT POWER RANGE (IN WATTS)
! FROM 0 TO 0.01 WATTS
Description:
If linear units are selected for analog output control, this command selects the beginning and
end points of the power levels which will be assigned corresponding voltages at the analog
output. Also see MEM:VOLT below.
Syntax:
MEMory[:TABLe]:POWer?
Example:
OUTPUT @PWR_MTR;MEM:POW? ! QUERIES ANALOG OUT POWER RANGE (IN DBM)
Response:
Response is two dBm values separated by a comma indicating analog output range.
Description:
This query reports the end points of power levels of the analog output configuration. When
log units are selected, the units are dB or dBm. When linear units are selected the units are
Watts.
MEM:VOLTage
Syntax:
MEMory[:TABLe:VOLTagespace<start value from -10 to +10 V>comma<stop value from -10 to +10 V>
Example:
OUTPUT @PWR_MTR;MEM:VOLT -7,2 ! SETS ANALOG OUT VOLTAGE RANGE FROM
! -8 TO 2 VOLTS CORRESPONDING TO POWER
Description:
This command is not units dependent. It selects the beginning and end points of the voltage
levels desired to be present at the analog output. These voltages correspond to the power
end points that are defined with either MEM:VOLT or MEM:POW.
Syntax:
MEMory[:TABLe:VOLTage?
Example:
OUTPUT @PWR_MTR;MEM:VOLT? ! QUERIES ANALOG OUT VOLTAGE RANGE
Response:
Two voltage values separated by commas indicating analog output range.
Description:
This query reports the end points of the voltages configured for analog output operation.
