Agilent Technologies E1441A ADJust, Only valid with Option, Subsystem Syntax PHASe

PHASe

Only valid with Option 001

The PHASe command subsystem is valid only with the Phase-Lock option (option 001). This command allows you to control the phase offset of the output waveform. You can also enable the phase-lock error reporting to generate an error when phase-lock is lost (unlocked). See the STATus command for querying the questionable data registers and status byte to verify the unlock condition.

:REFerence :UNLock:ERRor:STATe OFF ON :UNLock:ERRor:STATe?

:ADJust

PHASe:ADJust <radians><degrees>DEG MINMAX adjusts the phase offset of the output waveform in radians or in degrees (must specify DEG following the parameter if specified in degrees). Select from -2πradians to +2π radians. The default is 0 radians. MIN = -2πradians; MAX = +2π radians. The phase offset setting is stored in volatile memory.

Parameters

Parameter Name	Parameter Type	Range of Values	Default Units
radians	numeric	-2πto +2π	radians
degrees	numeric	-360°to +360°	must specify
			DEG

Comments • You must specify "DEG" following the phase value if you specify the phase in degrees instead of radians. For example, to specify a -90°phase offset, use the following command:

PHAS:ADJ -90 DEG

•For sine, square, triangle, and ramp waveforms:

Zero (0) radians is the point at which the waveform crosses zero volts (or the dc offset value) in a positive-going direction.

•For arbitrary waveforms:

Zero (0) radians is the first point downloaded to memory.

•The phase adjustment for phase-lock is independent of the burst phase as set by the BM:PHAS command. See “Burst Modulation” on page 33. for more information.
