Changing The Frequency And Sample Clock - Racal Instruments 3151 User Manual

3151 And 3151A User Manual
Changing the
Frequency and
Sample Clock
Use the following command to change the frequency for standard
waveforms and sample clock for arbitrary waveforms:
FREQuency {<frequency> | MINimum | MAXimum}
MIN selects the lowest frequency allowed for the currently active
function. MAX selects the highest frequency allowed for the currently
active function. The default frequency setting is 1 MHz for all
functions.
The query:
FREQuency?
Queries the frequency setting for the standard function currently
active and returns a value in hertz.
The command:
FREQuency:RASTer {<frequency> | MINimum |
MAXimum}
sets the sample clock frequency for the user and sequenced
functions. MIN selects the lowest frequency allowed for the currently
active segment or sequence. MAX selects the highest frequency
allowed for the currently active segment or sequence. The default
sample clock frequency setting is 1 MHz for all functions.
Note that the output frequency depends on the number of points
specified in the waveform. The output frequency can be computed
using the following formula: Output Frequency = Sample Clock /
Number of points in the active segment.
The query:
FREQuency:RASTer?
queries the sample clock frequency setting for the arbitrary segment
or sequence currently active and returns a value in hertz.
