negative time interval values in seconds multiplied by the nominal input frequency. This default
behavior can be modified with various command-line options, described below in alphabetical order.
/am:<true | false>
By default, TSERVE performs AM noise measurements as well as phase noise measurements, as
in the TimeLab GUI application. AM measurements can be disabled to reduce CPU workload by
specifying
/am:false
on the command line. The show amspectrum and show amspurs
commands will display the error message
AM measurements are not enabled
in this case.
/ch:<chanexpr>
Specifies the channel configuration to be used for stability measurements.
By default, the channel expression is 3-1 , indicating that a DUT connected to the 53100A’s
channel 3 input (or the DUT input splitter that drives it) should be measured using the reference
connected to the channel 1 input or REFERENCE input splitter. It is possible to return data for
up to 4 channel pairs, sampled simultaneously. For example, data for a three-cornered hat
measurement of oscillators connected to channels 1, 2, and 3 could be obtained by specifying
/ch:1-2,2-3,3-1
on the command line as shown in Figure 74 below.
