9500B
Calibration Manual
46
Equipment Requirements
•
The UUT Model 9500B Mainframe, with 9510 or 9530 Active Head.
•
A high resolution Standards DMM with RMS AC Voltage accuracy of ±0.3 % or
better, between 0.5 V and 2 V, at 1 kHz and 45 kHz. Example: Model 1281
Digital Multimeter.
•
An adaptor to convert from BNC to 4mm leads. Example: Model 4955
Calibration Adaptor.
•
Short, high-quality 4 mm leads.
Interconnections
Refer to Figure 5 given below.
Verification Setup
1.
Connections:
Ensure that the 9500B is connected to the DMM as
shown in Figure 4, or via a similar BNC-4 mm
adaptor, and that both instruments are powered on
and warmed up.
2.
9500B:
Ensure that the 9500B is in MANUAL mode and
then select the Sine function (
Χ
key). Select the
required output Signal Channel (50
Ω
Load), trigger
channel and Trigger Ratio (if required).
