:MEASure[:SCALar][:VOLTage]:PERiod?

[<expected_value>[,<resolution>]][, (@1)|(@2)|(@3)]

Measures Period.

The measurement arming mode is set to “digits.” The Counter uses the

<expected_value> and <resolution> parameters to configure the number of digits

of resolution arming setting.

The Channel 1 or Channel 2 trigger settings are coupled so that the measurement

channel has auto-trigger enabled at 50% with a positive slope.

Ch1, Ch2

<expected_value>

range: 4.4 ns to 10.0 sec

resolution: <expected value> should be within 10% of input period

for optimum arming configuration

default: 100 ns

Ch1, Ch2 <resolution>

description: value indicates decade corresponding to least significant

digit of the result

range: 1E-23 to 1E-2 sec

value which indicates 3 to 15 digits of resolution for the

specified <expected value>

resolution: <resolution> should use a mantissa of 1.0 and be an even

power of 10

default: value which indicates 4 digits of resolution for the

specified <expected_value>
