• 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

• Press
CLEAR
to clear the softkey menu, and to see the full screen.
Note:
The 20 kHz bandwidth limiter rejects calibrator noise. It does not affect the gain
accuracy at a 50 Hz input signal
3. Using
TIMEsns
change the time base to select manual time base ranging, and lock
the time base on 10 ms/div.
4. Press
: Using
MOVE
and
MOVE
move the Input A ground level (indicated by
the zero icon
in the left margin) to the center grid line.
5. Using
mV
RANGE
and
RANGE
set the Input A sensitivity range to the first test point in Table
4-1.
6. Set the 5500A to source the appropriate initial ac voltage.
7. Adjust the 5500A output voltage until the displayed Input A trace amplitude is 6
divisions.
8. Observe the 5500A output voltage and check to see if it is within the range shown
under the appropriate column.
9. Continue through the test points.
10. Next check channel B, C or D in succession:
Connect channel B, C or D input to 5500A,
Press
TRIGGER
and select B, C or D as trigger source with
F1
,
Press B, C or D to assign vertical range and move to channel B, C or D,
Observe the 5500A output voltage and check to see if it is within range.
11. When you are finished, set the 5500A to 0 (zero) Volt, and to Standby.
