H
Press the front-panel button that corresponds to the next channel
you are to confirm.
H
Press MEASURE.
H
Press the main-menu button Select Measurement for CHx; then
press the side-menu button Mean. (You will have to press MORE
several times to access the Mean measurement.)
H
Move the test hook up to the channel you select.
H
Set the vertical SCALE to 100 mV.
H
Set the vertical POSITION to 0 V.
H
Press the VERTICAL MENU button and then the Offset main-
menu button. Set the offset to 0 V.
b.
Set the generator: Set the DC calibration generator to +0.35 V.
c.
Record Measurement: Read the mean at the measurement readout
and record this number on a piece of scratch paper.
d.
Set the generator: Set the DC calibration generator to –0.35 V.
e.
Check against limits: Do the following subparts in the order listed.
H
Use this formula to calculate voltage measurement accuracy.
700 mV – (mean from step c – (present mean))
For example:
700 mV – (347 mV – (–358 mV)) = –5 mV
H
CHECK that the voltage measurement accuracy is within
"
20.8 mV.
f.
Test all channels: Repeat substeps a through e for all channels.
3.
Disconnect the hookup:
a.
Set the generator output to 0 V.
b.
Then disconnect the cable from the generator output at the input
connector of the channel last tested.
Check Analog Bandwidth

Equipment Required for TDS 460:
One high-frequency leveled sine-wave
generator and its leveling head (Item 12), one 50
W
precision cable (Item 5),
and two 10X attenuators (Item 1).
Prerequisites:
See page 4-13.
