Edged Aberration Verification
This procedure uses:
• Tektronix 11801 oscilloscope with SC22/26 sampling head
• Output cable supplied with the SC1100
To do edge aberration verification:
1. Make sure that the SC1100 is in the edge mode (the edge menu is shown in the
display), and set it to output 1 V p-p @ 1 MHz.
2. Push .
3. Connect the Calibrator to the oscilloscope as shown in Figure 7-8.
4. Set the oscilloscope vertical gain to 10 mV/div and horizontal time base to 1 ns/div.
5. Set the oscilloscope to show the 90 % point of the edge signal. Use this point as the
reference level.
