Appendix B: Performance Verification
B–8
TDS 340A, TDS 360 & TDS 380 User Manual
Equipment Required: One leveled sine wave generator (Item 7 or 8), one 50 W
precision cable (Item 2), and one 50 W termination (Item 1).
Time Required: Approximately 20 minutes.
Prerequisites: See page B–5.
Procedure:
1. Connect, through a 50 W precision cable and a 50 W termination, the sine
wave output of a leveled sine wave generator to CH 1 (see Figure B–3). Set
the output of the generator to a reference frequency of 50 kHz.
NOTE. If you are verifying a TDS 380, you need a leveled sine wave generator
with a 400 MHz output frequency. Refer to Sine Wave Generator Leveling
Procedure on page B–14 for information on obtaining a leveled output from an
unleveled sine wave generator.
