Test 1: Channel 1 Frequency Sensitivity
Repeat steps 5, 6, and 7 for each of the remaining frequencies specified for
Test 1a. Don't forget to change the power level when performing the
1 KHz test (–19.2 dBm/25 mV).
If all of the frequency values you recorded for Test 1a are correct, mark
Pass in the Performance Test Record for Test 1a. If any of the frequency
readings you recorded are incorrect, mark Fail in the Performance
Test Record.
Do not disconnect the cable from the instrument's Reference 10MHz
•
connector. This connection is used in the following test.
• Do not turn off the instrument. Turning the instrument off and back on
resets the reference oscillator (REF OSC) selection to internal (INT)
and the channel selection to CHANNEL 2.

Test 1b: 50 MHz to 125 MHz Frequency Sensitivity

Connect an Agilent 10100C 50 Ω Feedthrough Terminator to the
CHANNEL 1 input connector on the instrument's front panel (refer to
Figure 1-4 for steps 1 through 9).
