4.15-2 Section 4: Using the Model 9500B — Auxiliary Input
Final Width = 215mm
Descriptions assume 9500B/1100
4.15.6.1 Introduction
The calibration procedure consists of routing a
signal from a user's source to a specified channel
input, as required by the oscilloscope
manufacturer's calibration procedure.
4.15.6.2 Interconnections
a. Use the appropriate active head to connect
from the required 9500B signal output
channel to the UUT input channel.
b. Connect the user's source to the
'AUXILIARY INPUT' SMA connector on
the 9500B rear panel.
4.15.6.3 User's Signal Source,
9500B and UUT Scope
Setup
The following procedures assume that the
9500B instrument is in Manual Mode. It is also
assumed that the user will be familiar with
front panel operation. In case of difficulty, re-
read the paragraphs earlier in this Section 4.
1. Preparation
Ensure that all instruments are powered ON
and warmed up.
2. UUT 'Scope
Select the required function requiring the user's
specific signal .
3. 9500B
Ensure that the 9500B is in Auxiliary Input
with Output OFF. If in any other function,
press the 'Aux' key on the right of the
'OSCILLOSCOPE CALIBRATOR' panel,
then the
AUX IN
soft key on the right of the
screen.
4. User's Signal Source
Set up the signal source to provide the required
signal to the 9500B rear panel 'Auxiliary Input'
(refer to the Auxiliary Input Routing
Specification in para 4.15.5.2).
4.15.6.4 Sequence of Operations
Refer to the table or list of UUT Oscilloscope
calibration points in the UUT Oscilloscope
Manufacturer's Calibration Guide.
Follow the sequence of calibration stages as
directed by the guide, and carry out the
following operations (1) to (5) at each stage.
1. User's Signal Source
Ensure that the correct signal is being
output.
2. UUT 'Scope
a. Select the correct channel for the cal point.
b. Select the correct range for the cal point.
3. 9500B Set Output ON.
4. UUT 'Scope
a. Adjust the sweep speed and trigger level
for a stable display.
b. Observe and record the UUT's response to
the user-specific signal as detailed in the
UUT Oscilloscope Manufacturer's
Calibration Guide.
5. 9500B Set Output OFF.
