6.6.4.14
[SOUR]:PHAS[:ADJust](?) <DNPD>
Purpose
This command is used to set the phase angle of the 9100 output, with respect to 'Phase Lock In', when operating in either 'AC Voltage'
or 'AC Current' function.
<DNPD>
The 'decimal numeric program data' is a number which sets the required phase angle of the selected operation, expressed in units
of Degrees. The Phase angle is resolved in increments of 0.01
°
, over a range of acceptable values from -180
°
to +180
°
.
Example:
An 'AC Voltage' function output phase angle could be programmed by:
FUNC:{SIN|IMP|TRI|TRAP|SYMS};:VOLT <DNPD>;:FREQ <DNPD>;:PHAS <DNPD>;:PHAS:INP ON;
Function Change,
∗
RST
Common Command and Power-up
The 9100 phase angle is set to zero degrees (equivalent to
PHAS:ADJ 0
). For details of operation and parameter limitations, refer
to Volume 1, Section 4, Sub-Sections 4.4 and 4.6 (AC Voltage and AC Current).
Response to Query Version
The instrument will return the present phase angle value for the selected operation, dependent upon the
most-recent
VOLT
or
CURR
command. The returned number will be in standard scientific format (for example: 90
°
would be returned as
9.0E1
).
6.6.4.15
[SOUR]:PHAS:INP[:STATe](?) <CPD>{OFF|ON|0|1}
Purpose
The 9100 AC Voltage or AC Current output can be phase-shifted from a reference-phase input via the 'PHASE LOCK IN' plug on
the rear panel (by a phase angle set by the
PHASe:ADJust
command — see 6.6.4.14 earlier).
This command switches the 9100: either to free run; or to be locked to the reference phase.
<CPD>
The 'character program data' switches the 9100: either to free run (
OFF
or
0
); or to be locked to the reference phase, after setting
the phase angle (
ON
or
1
).
Example:
An 'AC Voltage' function output phase angle could be programmed by:
FUNC:{SIN|IMP|TRI|TRAP|SYMS};:VOLT <DNPD>;:FREQ <DNPD>;:PHAS <DNPD>;:PHAS:INP ON;
Function Change,
∗
RST
Common Command and Power-up
The 9100 state changes to free run (equivalent to
PHAS:INP {OFF
|
0}
). For details of operation and parameter limitations, refer
to Volume 1, Section 4, Sub-Sections 4.4 and 4.6 (AC Voltage and AC Current).
Response to Query Version
The instrument will return the present 'phase input state' setting:
{OFF|ON}
.
