Frequency Accuracy Test
6-12.
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
Functions" in Chapter 3 of this manual.)
2.
Open Spy Window Select the Spy command from the Utilities menu. Select
channel 0101 (instrument 01, channel 01) from the Channel list. Click OK to
open the Spy window.
3.
Verify Accuracy Configure the 5700A for the output values below and
verify the Spy window measurement is between the minimum and maximum
values. Change the channel 1 range as required (see Step 1).
