2-40 TDS5000B Series Specifications and PerformanceVerification

a. Hook up the test-signal source:Connect, through a 50 Ωprecision

coaxial cable, the output of the gen erator to CH 1. See Figure 2--16.

HIf using a time-markgenerator, set the output for 10 ms markers.

HIf using a sinewave generator, set the output for 1.2 V and 500 kHz.

b. Initialize the oscilloscope:Press the DEFAULT SETUP button.

c. Modify the initialized front-panelcontrol settings:

HSet the Vertical SCALE to 200 mV (or 500 mV with the optional

TektronixTG501A Time Mark Generator).

HSet the Horizontal SCALE to 80ns(100 ns for TDS5054BE).

HFrom the toolbar,click the Vert button; then click the Termination

50 Ωbutton.

HPressPUSH TO SET 50%.

HClick the Close button.

HUse the Vertical POSITION knob to centerthe test signal on the

screen.

HPress the TriggerMODE button to toggle it to NORMAL.

2. Confirm that the time base is within limits for accuracies:

a. Measurethe test signal:

HIf using a time-markgenerator, align the trigger T to the center

verticalgraticule line by adjusting the Horizontal POSITION. See

Figure 2--17on page 2--41.

HIf using a sine wave generator,align the rising edge of the sine wave

on the center graticulecrosshairs by adjusting the Horizontal

POSITION.

HFrom the toolbar,click the Horiz butt on, and select the HORIZON-

TAL tab.

HPress the Horizontal DELAYMode button to toggle it on. See

Figure 2--17on page 2--41.

HSet the delay timeto 10 ms. (Do this by clickingH oriz Delay and

on the keypad press10, then mfollowed by ENTER.)

b. Check long-term sample rate and delay time accuraciesagainst limits:
