HP WaterSkis E1412A, WaterSkis E1312A manual DBREFerence?, DBMREFerence?

:DB:REFerence

CALCulate:DB:REFerence <value>MINMAX stores a relative value in the dB Relative Register. You must turn on the math operation e.g., execute CALC:STAT ON before writing to the math register. You can set the relative value to any number between ± 200dBm (the MIN and MAX values). The dB reference is stored in volatile memory.

Example Set the DB Reference Value

CALC:STAT ON	Turn on the math operation.
CALC:DB:REF 60	Sets DB reference to 60 dBm.
CALC:FUNC DB	Select the DB math operation. You can select
	the calculate function at any time before or
	after enabling the calculate state.

:DB:REFerence?

CALCulate:DB:REFerence? [MINMAX] queries dB reference value.

Example Query the DB Reference Value Set for the DB Math Operation

CALC:DB:REF? Query the DB reference value.

:DBM:REFerence

CALCulate:DBM:REFerence <value>MINMAX selects the dBm reference value. Choose from: 50, 75, 93, 110, 124, 125, 135, 150, 250, 300, 500, 600 (default), 800, 900, 1000, 1200, or 8000 ohms. MIN = 50Ω. MAX = 8000Ω. You must turn on the math operation e.g., execute CALC:STAT ON before writing to the math register. The dBm reference is stored in non-volatile memory.

Example Set the DBM Reference Value

CALC:STAT ON	Turn on the math operation.
CALC:DBM:REF 135	Sets DBM reference value to 135.
CALC:FUNC DBM	Select the DBM math operation. You can select
	the calculate function at any time before or
	after enabling the calculate state.

:DBM:REFerence?

CALCulate:DBM:REFerence? [MINMAX] queries the dBm reference.

Example Query the DBM Reference Value Set for the DBM Math Operation

CALC:DBM:REF? Query the DBM reference value.
