7. When you are finished, set the 5500A to Standby.
Table 4-1. Input A,B Frequency Measurement Accuracy Test
5500A output, 600 mVpp Input A, B Reading
1 MHz 0.993 to 1.007 MHz
10 MHz 09.88 to 10.12 MHz
40 MHz 38.98 to 41.02 MHz
Note
Duty Cycle and Pulse Width measurements are based on the same
principles as Frequency measurements. Therefore the Duty Cycle and
Pulse Width measurement function will not be verified separately.
4.5.5 Input B Frequency Measurement Accuracy Test
Proceed as follows to test the Input B frequency measurement accuracy:
1. Connect the test tool to the 5500A as shown in Figure 4-4.

2. Select the following test tool setup:
• Press
select auto ranging (AUTO in top of display).
• Press to open the INPUT B MEASUREMENTS menu, and choose:
INPUT B: ■ ON | MEASURE on B: ■ Hz
• Press to open the SCOPE INPUTS menu.
• Press
to open the TRIGGER menu, and choose:
INPUT: ■ B | SCREEN UPDATE: ■ FREE RUN | AUTO RANGE: ■ >15HZ
3. Set the 5500A to source a leveled sine wave of 600 mV peak-to-peak (SCOPE
output, MODE levsin).
