4.6.12 Input B AC Voltage Accuracy (HF) & Bandwidth Test
Proceed as follows to test the Input B 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 4-7).
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 2
, and select
on B | 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 B sensitivity range on 500 mV/div.
3. Set the 5500A to source a sine wave, to the first test point in Table 4-11.
4. Observe the Input B reading and check to see if it is within the range shown under
the appropriate column of table 4-11.
5. Continue through the test points.
6. When you are finished, set the 5500A to Standby.
