9.8.2 Verifying the DC/Square Function:
Square Voltage
9.8.2.1 Summary
Equipment requirements are given at para 9.8.2.2 and test
interconnections at para 9.8.2.3.
The Square Function is verified by carrying out measurements of
amplitude in the sequence given at para 9.8.2.4, at the verification
points shown in Tables 9.8.2.1, 9.8.2.2 and 9.8.2.3.
9.8.2.2 Equipment Requirements
• The UUT Model 9500B Mainframe, with 9510 or 9530 Active
Head.
• A high resolution Standards DMM with RMS AC Voltage accuracy
of ±0.01% or better, from 2.5mV to 35V, at 1kHz.
Example: Model 1281 Digital Multimeter.
• An adaptor to convert from BNC to 4mm leads.
Example: Model 4955 Calibration Adaptor.
• Short, high-quality 4mm leads.
9.8.2.3 Interconnections
Refer to Fig 9.8.2.1 opposite.
9.8.2.4 Verification Setup
1. Connections Ensure that the 9500B is connected to the DMM as
shown in Fig. 9.8.2.1, or via a similar BNC-4mm
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 DC/Square; Square (Positive)
function (MANUAL mode entry default or
soft key). Select the required output Signal Channel
(1MΩ Load), trigger channel and Trigger Ratio (if
required).
