Counter Control
Commands
Use the following commands for programming the counter/timer
measuring function and its associated parameters. The counter/timer
function is created digitally however, it closely simulates a stand-alone
instrument so its functions are programmed just as they would be
programmed on a dedicated instrument. The specifications and
limitations of the counter/timer are specified in Appendix A. The
counter commands are summarized in Table 5-13.

Description
Programs the measurement function for the counter/timer. Each measurement can be set up with its gate
time (where applicable) and display mode.
Parameters

Default
Description
FREQuency
Discrete
FREQ
Will select the frequency measurement function. Frequency
is measured on continuous signal only. The result of the
frequency measurement has gate-dependent resolution.
The 3152B displays 7 digits of frequency reading in one
second of gate time. If the gate time is decreased, the
number of displayed digits decreases proportionally to the
gate time interval. Reduce the gate time when you want to
accelerate the reading process however, always make sure
that the period of the signal is smaller than the gate time
setting.
PERiod
Discrete
Will select the period measurement function. Period can be
measured on either continuous or non-repetitive signals.
Since the period of the signal is directly proportional to the
gating time, the number of displayed digits decreases
proportionally to the period of the signal. If you need to
have more resolution and you signal is repetitive, use the
period averaged measurement function. The best resolution
in period measurements is 100 ns.
