Selecting The Sample Clock Source; Programming The Output Amplitude And Offset - Racal Instruments 3151 User Manual

Selecting the
Sample Clock
Source
Programming the
Output Amplitude
and Offset
Using The Instrument 3-10
Use the following command to select the source for the sample clock
for the user and sequenced functions:
FREQuency:RASTer:SOURce {EXT | INT | ECLTRG0}
EXT selects an external clock source. The external source is applied
to the front panel CLOCK IN connector. INT selects the internally
synthesized clock generator. ECLTRG0 selects a sample clock that
is available on the backplane. Note that ECLTRG0 is always the
active sample clock source when the Model 3151/3151A is set to
operate in phase synchronization mode.
The query:
FREQuency:RASTer:SOURce?
queries the sampe clock source setting and returns EXT, INT or
ECLT.
Use the following command to program the peak-to-peak amplitude
for the generated waveform.
VOLTage {<amplitude>|MINimum|MAXimum}
MIN selects the smallest amplitude. MAX selects the largest
amplitude. The default amplitude is 5.00 V (into 50Ω).
The query:
VOLTage?
Queries the output amplitude for the currently selected function and
returns a value in volts.
The command:
VOLTage:OFFSet <offset>
sets the offset for the currently active function. The default offset is 0
V.
The query:
VOLTage:OFFSet?
queries the output offset for the currently selected function and
returns a value in volts.
