Signal Acquisition System Checks

Check DC Voltage
Measurement Accuracy
TDS6000B Series Specifications and Performance Verification Technical Reference
These procedures check those characteristics that relate to the signal-acquisition
system and are listed as checked under Warranted Characteristics in Specifica-
tions. Refer to Table 4- -1 on page 4- -2 for test equipment specifications.
Equipment Two dual-banana connectors (Item 5)
required
One BNC T connector (Item 6)
One DC calibration generator (Item 9)
One SMA male-to-female BNC adapter (Item 20)
Two precision 50 Ω coaxial cables (Item 4)
Prerequisites The oscilloscope must meet the prerequisites listed on page 4- - 1
WARNING. The generator is capable of outputting dangerous voltages. Be sure to
set the DC calibration generator to off or 0 volts before connecting, disconnect-
ing, and/or moving the test hookup during the performance of this procedure.
Also, check that the calibrator does not have shorting straps installed between
the DC and sense outputs or grounds.
1. Install the test hookup and preset the instrument controls:
a. Hook up the test-signal source:
H Set the output of a DC calibration generator to off or 0 volts.
H Connect the output of a DC calibration generator through a
dual-banana connector followed by a 50
one side of a BNC T connector. See Figure 4- -1.
H Connect the Sense output of the generator through a second
dual-banana connector followed by a 50
the other side of the BNC T connector. Now connect the BNC T
connector to CH 1 through an adapter. See Figure 4- -1.
