Fluke 9500B - Use the 9500 B to Measure Load Resistance or Load Capacitance

4.16-2 Section 4: Using the Model 9500B — Load R and C Measurement
Final Width = 215mm
Descriptions assume 9500B/1100
4.16.6.4 Sequence of Operations
(Load Resistance)
Refer to the table or list of UUT Oscilloscope
Load Resistance measurement points in the
UUT Oscilloscope Manufacturer's Test/
Calibration Guide.
Follow the sequence of test stages as directed
by the guide, and carry out the following
operations (1) to (5) at each stage.
1. 9500B
a. Press the 'SIGNAL CHANNEL' screen
key on the bottom row.
b. Select the required signal channel.
c. Select the appropriate load (50Ω or 1MΩ)
using the toggle screen key in the bottom
right corner.
d. Press 'EXIT'.
2. UUT 'Scope
a. Select the correct channel for the test point.
b. Select DC Coupling if required.
3. 9500B
a. Set Output ON.
b. Read the Load Resistance value from the
screen.
4. UUT Response
Record the UUT channel load resistance at the
test point as detailed in the UUT Oscilloscope
Manufacturer's Test/Calibration Guide.
5. 9500B Set Output OFF.
4.16.6.1 Introduction
Both measurement procedures consists of
connecting an active head to each channel
input in turn, and checking that the resulting
resistance or capacitance reading is within
specification limits.
4.16.6.2 Interconnections
Use the appropriate active head to connect
from the required 9500B signal output channel
to the UUT input channel. No triggers are
required or available.
4.16.6.3 9500B and UUT Scope
Setup
1. Preparation
Ensure that both instruments are powered ON
and warmed up.
2. UUT 'Scope
Select the required function for Load Resistance
or Load Capacitance measurement as required.
3. 9500B
Ensure that the 9500B is in Load Resistance or
Load Capacitance Measurement function with
Output OFF. If in any other function, press the
'Aux' key on the right of the 'OSCILLOSCOPE
CALIBRATOR' panel, then the
or
soft key at the bottom of the screen.
