• High Frequency Digital Storage Oscilloscope: Tektronix 11801 with Tektronix SD-
22/26 sampling head
• 3 dB attenuator, 3.5 mm (m/f)
• BNC(f) to 3.5 mm(m) adapter (2)
• BNC cable supplied with the SC600
• second BNC cable
Connect the BNC cable supplied with the SC600 to the Calibrator Mainframe’s SCOPE
connector. Connect the other end of the BNC cable to one BNC(f) to 3.5 mm(m) adapter
then to the DSO’s sampling head through the 3 dB attenuator.
Using the second BNC(f) to 3.5 mm(m) adapter and BNC cable, connect the Calibrator
Mainframe’s TRIG OUT connector to the 11801’s Trigger Input. Refer to Figure 6-7.

Figure 6-7. Edge Rise Time Verification Setup
The Calibrator Mainframe should be in SCOPE mode, with the Edge menu on the
display. Press O on the Calibrator Mainframe to activate the output. Press the softkey
under TRIG to select the TRIG/1 External Trigger output. Program the Calibrator
Mainframe to output 250 mV @ 1 kHz. Set the DSO to these parameters:
Digital Storage Oscilloscope Setup
Main Time Base position (initial) 40 ns
Horizontal scale 500 ps/div
Measurement Function Rise Time
1. Program the Calibrator Mainframe to output the voltage and frequency listed in
Table 6-26. Press O on the Calibrator Mainframe to activate the output.
2. Change the vertical scale of the DSO to the value listed in the table. Adjust the main
time base position and vertical offset until the edge signal is centered on the display.
Record the rise time measurement in column A of Table 6-26.
