JITTer:LEVel:DEFine
Command :MEASure:JITTer:LEVel:DEFine {PERCent,<percentage_value> | UNITs,<level_value> | AVERage}
Defines the jitter sampling level. It may be specified as a percentage in the range of 30% to
70%, as an absolute amplitude level, or as the average amplitude of the test signal. If you
specify UNITs, the level value is interpreted as Watts or Volts depending on the type of input
channel selected: optical or electrical. For example, if a value of 500E-3 is entered, it will be
interpreted as 5 mW when applied to an optical channel and 5 mV when applied to an electri-
cal channel.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Query :MEASure:JITTer:LEVel:DEFine?
This query returns the current setting for the jitter sampling level.
Returned Format [:MEASure:JITTer:LEVel:DEFine] <value><NL>
Example :MEASure:JITTer:LEVel:DEFine PERCent,40
JITTer:PATTern?
Query :MEASure:JITTer:PATTern?
Returns definite-length block data. The data block contains the pattern as determined by the
instrument. Each value in the pattern is a single byte. Values in the pattern are the ASCII
values for '0' and '1' (30 hex and 31 hex, respectively). The data block is followed by a termi-
nator character, 0A hex (linefeed). This query will return an incomplete description of the
pattern if all of the data needed to determine the pattern has not yet been acquired. This
query produces an error if jitter signal type is set to clock signal.
Use the :MEASure:JITTer:DDJVsbit? query to return the DDJ values. Use the :MEASure:JITTer:EBITs?
query to return the bit numbers.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Returned Format [:MEASure:JITTer:PATTern] <value><NL>

JITTer:PJ?
Query :MEASure:JITTer:PJ?
Returns the periodic jitter, PJ (
δ-δ), value measured on the current source.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Returned Format [:MEASure:JITTer:PJ] <value><NL>
