Using The Instrument 3-13
HCLock Generates a trigger signal at intervals
equal to half of the period of the sample
clock. This option is useful for
synchronizing two-point waveforms on an
oscilloscope (sine and square waveforms
above 10 MHz).
The query:
OUTPut:SYNC:SOURce?
queries the validating signal source for the SYNC output and returns
BIT, LCOM, SSYN or HCL.
Selecting the SYNC
Position
The SYNC output can be programmed to output the SYNC signal at
any point along the output waveform. This function is available in
USER or SEQ modes only. Use the following command to select
the SYNC output position:
OUTPut:SYNC:POSition:POINt <value>
The SYNC position can be selected from point 0 to the last point of
the active waveform. SYNC position has to be programmed for each
segment. The default SYNC position is 6 points from the end of the
segment.
The query:
OUTPut:SYNC:POSition:POINt?
queries the output SYNC position and returns an integer value.
Using the Built-In
Standard
Waveforms
The Standard Waveform commands control the various parameters
of the active Standard Waveform. Standard waveform commands
operate in a similar fashion for each of the Standard Waveforms.
To simplify the description of this set of commands, only the
standard waveform commands for the PULSe function are
described. Use the same procedure to program parameters for the
SINe, TRIangle, RAMP, SQUare, SINC, GAUSsian, EXPonential
and DC waveforms.
The number of points used to define each Standard Waveform
varies. For SINe and SQUare:
Freq
#
200kHz Points = 500
Freq < 200kHz Points = 100MHz
Freq
Freq > 10MHz Points = 10
For RAMP, PULSE, GAUSSian and EXPonential:
Freq
#
100kHz Points = 1000
Freq > 100kHz Points = 100MHz
