FUNCtion Subsystem
l Limits due to Output Coupling: If two channels are coupled, limitations of setting the levels of both channels will be
checked before a change in level is executed. In this case, if a change in level would exceed a LIMIT setting, or
instrument output specifications for either channel, the level is clipped to the maximum (or minimum) allowable
value and a "Settings conflict" error will be generated.
l To invert the waveform relative to the offset voltage, use OUTPut[1|2]:POLarity.
[SOURce[1|2]:]FUNCtion:ARBitrary:SRATe {<sample_rate>|MINimum|MAXimum}
[SOURce[1|2]:]FUNCtion:ARBitrary:SRATe? {MINimum|MAXimum}
Sets the sample rate for the arbitrary waveform.
Parameter Typical Return
1 µSa/s to 250 MSa/s, default 40 kSa/s. Limited to 62.5 MSa/s if FUNC-
tion:ARBitrary:FILTer is OFF.
+1.000000000000000E+04
Set sample rate to 10 kSa/s:
FUNC:ARB:SRAT 1e4
l The sample rate and frequency parameter are not coupled when playing an arbitrary waveform segment. The con-
cept of frequency does not apply for arbitrary waveform sequences.
l Setting a sample rate when not in the ARB mode will not change the frequency. For example, if the current func-
tion is sine, setting sample rate has no effect until the function changes to ARB.
l The maximum sample rate depends on the filter applied to the arbitrary waveform. See FUNC-
tion:ARBitrary:FILTer for details.
[SOURce]:FUNCtion:ARBitrary:SYNCh
Causes two independent arbitrary waveforms to synchronize to first point of each waveform (two-channel instru-
ments only).
Parameter Typical Return
(none) (none)
Load an internal haversine waveform into channel 1 and a custom arbitrary waveform from a USB drive into channel
2. Set both sample rates to 100 kSa/s and then synchronizes both channels to the first point of each waveform:
