TDS 500D, TDS 600B & TDS 700D Performance Verification and Specifications

H CHECK that the Ch2 High readout is ≥1.0 volt and that the Ch2

Low readout ≤0.25 volts.

H Enter high and low voltages on the test record.

Check output

d. Check Delayed Trigger output against limits: See Figure 1–21.

H Move the precision 50 W cable from the rear-panel Main Trigger

Output BNC to the rear-panel Delayed Trigger Output BNC.

H CHECK that the Ch2 High readout is ≥1.0 volt and that the Ch2

Low readout ≤0.25 volts.

H Enter high and low voltages on test record.

H Press the side-menu button  to select the 1 MW setting. (This step

is not required on the TDS 794D – proceed to step 3.)

H Press CLEAR MENU.

H CHECK that the Ch2 High readout is ≥2.5 volts and that the Ch2

Low readout is ≤0.7 volts.

H Enter high and low voltages on test record.
