4.6.10 Input A AC Voltage Accuracy (HF) & Bandwidth Test
Proceed as follows to test the Input A high frequency automatic scope ac voltage
measurement accuracy, and the bandwidth:
1. Connect the test tool to the 5500A as for the previous test (see Figure 4-5).
2. Select the following test tool setup:
• Recall the created SETUP 1 (see section 4.4.3): press
, RECALL ,
select
SCREEN+SETUP 1 , press RECALL SETUP .
• Press
, then press READING 1 , and select on A | V ac.
• Press
to select autoranging (AUTO in upper right LCD edge)
• Using
and change the sensitivity range to select manual sensitivity
ranging, and lock the Input A sensitivity range on 500 mV/div. (
AUTO in upper
right LCD edge disappears)
3. Set the 5500A to source a sine wave, to the first test point in Table 4-9.
4. Observe the Input A reading and check to see if it is within the range shown under
the appropriate column.
5. Continue through the test points.
6. When you are finished, set the 5500A to Standby.
