Measures Frequency.
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.

.100 Hz to 225 MHz
<expected value> should be within 10% of input
frequency for optimum arming configuration
10 MHz
value indicates decade corresponding to least significant
digit of the result
1E-16 to 1E6 Hz
value which indicates 3 to 15 digits of resolution for the
specified <expected value>
<resolution> should use a mantissa of 1.0 and be an
even power of 10
