8. FREQUENCY ACCURACY

Description

This test checks the frequency accuracy of the E5071C test-port output signal.
The frequency accuracy is checked at several frequencies with a frequency
counter. Since the E5071C employs a PLL frequency synthesizer for the signal
source, a Frequency Accuracy Test at certain frequency points can verify the
accuracy for the entire frequency range.

1. The DSG (Device Substitution Group) is listed below the equipment descrip-
tion, if applicable. These devices are required to be mapped in TME to execute
a test. DSGs require either GPIB communication or are important for dynamic
measurement uncertainty calculations. N/A refers to required equipment that
is not mapped as DSGs in TME.
2. Over 8.5 GHz are Options 2D5/2K5/4D5/4K5.
3. Up to 8.5 GHz are Options
230/235/430/435/240/245/440/445/260/265/460/465/280/285/480/485.
4. If the frequency counters have high-stability oven timebase options installed
(53132A Option 010 or 012, 53131A/53181 Option 010, 53151A Option 001),
then it is not necessary to require an external 10 MHz reference. To use the
frequency counters high stability timebase, select "Internal Reference" when
mapping the Frequency Standard DSG.
