PHASe1:LOCK {OFF|ON|0|1}(?)
HS Syntax: 0820A<0|1>(?)
Description
This command will turn the backplane synchronization sequence on and off. This command requires that
another 3152B is plugged in the same chassis. The location of the two instruments is not critical for them to
synchronize. Using this synchronization method, the sample clock is placed on the ECLTrg0 line and the
synchronization signal is place on ECLTrg0 and therefore, if you intend to use this synchronization method,
make sure that these two backplane lines are not used by other modules.

Description
0-1
Discrete
0
Turns the backplane synchronization on and off
Response
The 3152B returns 0 or 1 depending on the current backplane synchronization setting.
PHASe1:ADJust <phase>(?)
HS Syntax: 0810A<float>(?)
Description
Programs the phase offset between the master and the slave units where the master is the reference
waveform and the phase of the slave instruments are shifted in reference to the master instrument.

Default
Description
<phase>
0 to 360
Numeric
0
Programs the phase offset between the slave and the
master instrument. The phase is programmed in units
of degrees (
°
). Note however, that the phase offset
resolution depends on the number of points that create
the waveform. For example, waveform that is made of
1024 points can be shifted with increments of 0.35
°
,
but another waveform that has only 100 points can be
shifted with increments of 3.6
°
.
