PTER?
Query PTER?
This query returns the current value of the Precision Timebase Event Register as a decimal
number and also clears this register. Bit 0 (LOSS) of the Precision Timebase Event Register is
set when loss of the time reference occurs. Time reference is lost when a change in the ampli-
tude or frequency of the reference clock signal is detected. The Precision Timebase Event
Register is read and cleared with the PTER? query.
When the LOSS bit is set, it in turn sets the PTIME bit (bit 11) of the Operation Status Regis-
ter. Results from the Precision Timebase Register can be masked by using the PTEE com-
mand to set the Precision Timebase Event Enable Register to the value 0. You enable the
LOSS bit by setting the mask value to 1.

PRINt
Command :PRINt
This command outputs a copy of the screen to a printer or other device destination, such as a
file, specified in the HARDcopy subsystem. You can specify the selection of the output and
the printer using the HARDcopy subsystem commands. See *OPC (Operation Complete)
command on page 3-5 for synchronization of PRINT operations.
Example 10 OUTPUT 707;”:PRINT”
RECall:SETup
Command :RECall:SETup <setup_memory_num>
This command recalls a setup that was saved in one of the analyzer’s setup memories. You
can save setups using either the STORe:SETup command or the front panel.
<setup_memory_num> is the setup memory number, an integer, 0 through 9.
Example 10 OUTPUT 707;":RECall:SETup 2"
RUN
Command :RUN [CHANnel<N>]
This command starts the instrument running where the instrument acquires waveform data
according to its current settings. Acquisition runs repetitively until the analyzer receives a
correspondent STOP command. <N> is an integer, 1 through 4. The execution of the RUN
command is subordinate to the status of ongoing limit tests. (see commands ACQuire:RUNTil
on page 6-4, MTEST:RUNTil on page 17-6, and LTESt:RUNTil on page 15-4). The RUN com-
mand will not restart a full data acquisiton if the stop condition for a limit test has been met.
