The Edge Function
The Edge function is used for calibrating the pulse response for your oscilloscope. To
reach the Edge menu, press the softkey under MODE until “edge” appears.

You can press the MODE softkey to cycle through the functions in the order shown, or
you can press
P
to return directly to the SCOPE menu.
Each option in the Edge menus is described below.
•
OUTPUT @ SCOPE terminal (50
Ω
) Indicates the location and impedance of the
signal output. If the signal does not appear on the oscilloscope, press
O
. To
disconnect the signal, press
Y
.
You cannot change the output impedance in Edge mode.
•
TD PULSE Press once to thrn the Tunnel Diode Pulser drive signal on, again to
turn the Pulser drive off. This signal sources up to 100 V p-p to drive a Tunnel Diode
Pulser (Fluke Part Number 606522, Tektronix 067-0681-01, or equivalent.
•
TRIG If you are using the external trigger, use this key to toggle the trigger off and
on. When on, the reading will show “/1” which indicates that the external trigger is at
the same frequency as the edge output. The external trigger can be useful for many
digital storage oscilloscopes that have difficulty triggering on fast rise time signals.
•
MODE Indicates you are in Edge mode. Use the softkey to change modes and open
the corresponding menus for the other four oscilloscope calibration modes.
Pulse Response Calibration Procedure for an Oscilloscope
This sample procedure shows how to check the oscilloscope’s pulse response. Before you
check your oscilloscope, see your oscilloscope’s manual for the recommended calibration
settings.
Before you start this procedure, verify that you are running the oscilloscope option in
Edge mode. If you are, the Control Display shows the following menu.

Perform the following sample procedure to calibrate the pulse response.
