TDS 500D, TDS 600B & TDS 700D Performance Verification and Specifications
Press the side-menu button Lower Limit.
Use the general purpose knob to increase the Lower Limit readout
until triggering is lost.
CHECK that the Lower Limit readout, after the oscilloscope loses
triggering, is within 3.5 ns to 6.5 ns, inclusive.
Enter time on test record.
Use the keypad to return the Lower Limit to 2 ns and reestablish
triggering.
Press the side-menu button Upper Limit; then use the general
purpose knob to slowly decrease the Upper Limit readout until
triggering is lost.
CHECK that the Upper Limit readout, after the oscilloscope loses
triggering, is within 3.5 ns to 6.5 ns, inclusive.
Enter time on test record.

3. Confirm the trigger system is within time-accuracy limits for pulse-glitch or
pulse-width triggering (horizontal scale >1 s):
a. Set upper and lower limits that ensure triggering at 250 kHz:
