show date
Returns the current date/time information as reported by the TSERVE host OS, as shown
in the example below (Figure 80):
The date and time formats are determined by the dateformat and timeformat
properties, respectively.
- show dateformat
- show timeformat
Both of these commands return the date and time formats, as established by the
dateformat
and
timeformat
properties (Figure 81):
- show fcounter
Returns the current reference frequency and frequency count chart at all available
averaging times up to 1000 seconds (Figure 82):
The display precision is 13 digits to the right of the decimal point for 1-second averaging
times at all DUT input frequencies. At DUT input frequencies of 5 MHz and above, 15
digits are displayed for averaging times longer than 10 seconds. 14 digits are displayed
under all other conditions.
As with the TSC 51XXA phase noise test sets, accurate frequency counts with reference
frequencies other than multiples of 100 kHz require the actual reference frequency to
be specified. This can be done by a Telnet client with the
set referencefreq
command,
or by using the
/referencefreq
command-line option on the server.
