Default Value which indicates 4 digits of resolution for the specified
<expected value>
Range 1E-7 Hz ~ 1E7 Hz (15 to 3 digits of resolution)
Resolution <resolution> should use a mantissa of 1.0 and be an even
power of 10
<source list> Default (@1)
Range (@1|@2|@3)
:MEASure[:SCALar][:VOLTage]:FREQuency:RATio?
[<expected_value> [,<resolution>]][,(@1),(@2)|(@1),(@3)|(@2),(@1)|(@3),(@1)]
Sets the measurement arming to “digits” and measures the frequency ratio between two inputs.
The <expected value> and <resolution> parameters are used to configure the number of digits
of resolution arming setting.
