Pulse Response Calibration Using A Tunnel Diode Pulser; The Leveled Sine Wave Function - Fluke 5500A Operator's Manual

8-33. Pulse Response Calibration Using a Tunnel Diode Pulser

You can use the calibrator to drive a tunnel diode pulser (Fluke Part Number 606522, or
Tektronix 067-0681-01, or equivalent), allowing you to check for pulse edge rise times
as fast as 125 ps.
The calibrator sources a maximum pulser drive signal of 100 V p/p at 100 kHz. The
recommended (and default) output setting is 80 V p/p at 100 kHz.
Perform the following procedure to use a tunnel diode pulser:
1. Connect the calibrator, tunnel diode pulser, and oscilloscope as shown in Figure 8-2.
2. With the SC600 Option in EDGE mode, press the TDPULSE softkey to "on".
3. Press .
4. Rotate the control on the pulser box to the minimum setting necessary to trigger a
reading.

8-34. The Leveled Sine Wave Function

The Leveled Sine Wave (LEVSINE) function uses a leveled sine wave, whose amplitude
remains relatively constant over a range of frequencies, to check the oscilloscope's
bandwidth. When you check your oscilloscope, you change the wave's frequency until
the amplitude displayed on the oscilloscope drops 30%, which is the amplitude that
corresponds to the -3 dB point. Default values are 30 mV p/p, 50 kHz.
