Measure Commands
JITTer:FREQuency:COMPonents?
JITTer:FREQuency:COMPonents?
Query
:MEASure:JITTer:FREQuency:COMPonents?
Returns a comma-separated list (as a string) of the detected frequency components. For
each component, the format is magnitude, frequency, subrate. Subrate is either the string
“rate/N” where N is the subrate number, or “-----” for asynchronous components. Both the
magnitude and frequency values have units appended to them. Set the instrument in single
sweep mode or send the DIGitize root-level command before sending this query to ensure
valid measurement data exists.
Restrictions
Jitter mode. Software revision A.04.10 and above (86100C instruments). Option 200,
Enhanced Jitter Analysis Software.
Returned Format
[:MEASure:JITTer:FREQuency:COMPonents] <string><NL>
The following is an example of a returned string:
930 fs,78.37 MHz,rate/127,420 fs,622.1 MHz,rate/16,210 fs,1.244 GHz,rate/8, 121 fs, 56.43 MHz,----”
Example
10 OUTPUT 707;”:MEASURE:JITTER:FREQUENCY:COMPONENTS?”
JITTer:FREQuency:MAXNumber
Command
:MEASure:JITTer:FREQuency:MAXNumber <max_async_freqs>
Sets the maximum number of asynchronous frequency components that the instrument will
detect. Detected components are analyzed in order of descending magnitude until the num-
ber of components specified with this command is obtained.
Restrictions
Jitter mode. Software revision A.04.10 and above (86100C instruments). Option 200,
Enhanced Jitter Analysis Software.
Query
:MEASure:JITTer:FREQuency:MAXNumber?
This query returns the maximum number of components setting.
Returned Format
[:MEASure:JITTer:FREQuency:MAXNumber] <max_async_freqs><NL>
Example
10 OUTPUT 707;”:MEASURE:JITTER:FREQUENCY:MAXNUMBER 10”
JITTer:FREQuency:SCAN
Command
:MEASure:JITTer:FREQuency:SCAN
Initiates a scan that calculates the absolute frequency of any significant asynchronous fre-
quency components up to the maximum number of components specified with the MEA-
Sure:JITTer:FREQuency:MAXNumber command. If the instrument is not in Jitter Mode (with
Option 200 installed), a “Settings Conflict” error is generated by this command.
Restrictions
Jitter mode. Software revision A.04.10 and above (86100C instruments). Option 200,
Enhanced Jitter Analysis Software.
Example
10 OUTPUT 707;”:MEASURE:JITTER:FREQUENCY:SCAN”
JITTer:ISI?
Query
:MEASure:JITTer:ISI?
Returns the inter-symbol interference value measured on the current source.
