Counter/Timer
Programming
Use the following command for programming the counter/timer
measuring function and other parameters. The counter/timer
function is created digitally however, it closely simulates a stand-
alone counter/timer 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.
COUNter:DISPlay:MODe{NORMal|HOLD(?)
Description
This command will program the display time mode for the counter/timer. The two modes are normal for
continuous display readings and hold for single reading after arming the counter input.
Parameters
Name Type Default Description
NORMal Discrete NORM Will select the continuous reading mode. In this case, the
counter input is self-armed, which means that every valid
signal that is sensed at the trigger input connector will be
counted and measured processed and results placed on
the interface port.
HOLD Discrete Will select the single reading mode. In this case, the
counter input is armed first and the first valid signal that is
sensed at the trigger input connector will be counted and
measured and its result processed and placed on the
interface port.
Response
The 2074 will return NORM, INV or COMP depending on the present polarity setting
COUNter:GATe<interval>(?)
Description
This command will program the gate time interval for frequency, period averaged and totalize in gated
mode. Measurements will be taken only after the input has been armed and valid signal available at the
input connector. Notice however, that the gate time internal must be larger than the period of the measure
signal.
Parameters
Name Range Type Default Description
<interval> 100e-6 to 1 Numeric 1 Will program the gate time interval in units of
seconds. In continuous mode, the counter is self-
armed and therefore every valid signal at the counter
input will open the gate and initiate a measurement
cycle. In hold mode, the counter must be armed
