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 4-8).
2. Select the following Test Tool setup:
• Recall the created setup (e.g. SETUP 1, see section 4.4.3): press
SAVE
,
F2
RECALL , select SCREEN+SETUP 1 , press
ENTER
to recall the setup .
• Press
SCOPE
, then press
F3
READING 2 , and select on B | V ac.
• Press
MANUAL
AUTO
to select autoranging (AUTO in upper right LCD edge)
• Using
mV
RANGE
and
V
RANGE
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.
