SOURce:FUNCtion:TRACe:NCYCles
Syntax
SOURce:FUNCtion:TRACe:NCYCles {<count>|MIN|MAX|DEF|INFinity}, (@<ch_list>)
SOURce:FUNCtion:TRACe:NCYCles? [{MIN|MAX}, ] (@<ch_list>)
Description
This command sets the number of trace cycles to be output from the specified channels on the 34951A Isolated DAC Module.
Used With:
34951A Isolated DAC Module
Parameters

Name |
Type |
Range of Values |
Default Value |
|
<count> |
Numeric |
Specify any value between 1 and 254, or 0 (continuous). MIN = 1, MAX = 254, INF = continuous |
0 (continuous) |
|
<ch_list> |
Numeric |
One or more channels in the form (@sccc).
|
This is a required parameter |
Remarks
If you have not associated a trace name with the specified channels (see SOURce:FUNCtion:TRACe[:NAME] command), an error is generated if you attempt to set the number of trace cycles.
The maximum rate for reloading a waveform is 1 second. Therefore, an external trigger may not be recognized if it comes too quickly (see SOURce:FUNCtion:TRIGger:SOURce command).
A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) will reset the count to 0 (continuous). In addition, storing the instrument state (*SAV command) will reset the count to 0 (continuous).
Return Format
The query command returns the count in the form "+1.00000000E+01" for each DAC channel specified. Multiple responses are separated by commas. For a continuous count ("0" or INFinity), the query command returns "+0.00000000E+00".
Examples
The following command sets the cycle count to 100 on DAC channels 1 and 2 in slot 4.
SOUR:FUNC:TRAC:NCYC 100,(@4001,4002)
The following query returns the cycle count on DAC channels 1 and 2 in slot 4.
SOUR:FUNC:TRAC:NCYC? (@4001,4002)
Typical Response: +1.00000000E+02,+1.00000000E+02
