Frequency Accuracy Test

Complete the following procedure to test the accuracy of the frequency function
for the 2640A and 2645A. Measurement accuracy applies to all channels, not just
the channel used for the test.
1. Configure Channel 1 for Frequency In NetDAQ Logger, configure channel
1 for frequency. There is no range selection for frequency as all frequency
measurements use Autoranging. (See "Configuring Analog Channel
