TDS 510A Performance Verification and Specifications
Press HORIZONTAL MENU. Now press the main-menu button
Time base; then press the side-menu button Delayed Triggerable.
Press the side-menu button Delayed Only.
Set the horizontal SCALE to 500 ps for the D (Delayed) time base.
Press the side-menu button Main Only.
c. Display the test signal:
Set the generator frequency to full bandwidth (500 MHz).
Set the test signal amplitude for about five divisions on screen. Now
fine adjust the generator output until the CH 1 Amplitude readout
indicates the amplitude is 500 mV. (Readout may fluctuate around
500 mV.)
Disconnect the leveling head at CH 1 and reconnect it to CH 1
through a 5X attenuator.
d. Repeat step 2, substeps b and c only, since only the full bandwidth
(500 MHz) is to be checked here.
NOTE
. You just checked the trigger sensitivity. If desired, you may repeat steps 1
through 4 for the other channels (CH2, CH3, and CH4).
5. Disconnect the hookup: Disconnect the cable from the channel last tested.
Output Signal Checks
The procedure that follows checks those characteristics of the output signals that
are listed as checked under Warranted Characteristics in Specifications. The
oscilloscope outputs these signals at its front and rear panels.
Equipment
Required Two 50 precision cables (Item 5)
One calibration generator (Item 10)
Prerequisites See page 1–15. Also, the oscilloscope must have passed Check DC
Voltage Measurement Accuracy on page 1–25.
Check Outputs — CH 3
Main and Delayed Trigger
