3 The Frequency A Function is used to measure the frequency
of the signal applied to INPUT A. A resolution of up to ten
digits can be selected with a gate time of 1 millisecond to
20 seconds depending on the resolution selected.
Frequency B Function
4 The Frequency B Function is used to measure the frequency
of the signal applied to INPUT B. A resolution of up to ten
digits can be selected with a gate time of 1 millisecond to
20 seconds depending on the resolution selected.
Frequency C Function (2151 only)
5 The Frequency C Function is used to measure the frequency
of the signal applied to INPUT C. A resolution of 0.1 Hz to
1 MHz can be selected with a gate time of 1 millisecond to
10 seconds depending on the resolution selected and
frequency being sampled.
Ratio C/B Function (2151 only)
6 The Ratio C/B Function is used to measure the ratio of the
frequency applied to INPUT C to that applied to INPUT B.
