Introduction
6-31
. The
Model 80RF-1 High
Frequency Probe,
Figure
6-9,
extends
the
frequency range
of the 8600A to
include
100
kHz to 500
MHz for
ac
voltage
measurements
from
0.25
to 30V rms. The 80RF-1
operates in conjunc-
tion with the dc voltage
ranges, and is connected
to the
8600A using
a
shielded
dual-banana plug and an
adapter.

6-33. Operating Notes
6-34.
The
straight
and the hooked tips supplied with the
probe are useful for making
voltage measurements up
to
100
MHz. For measurements
above 100
MHz use the
high
frequency
adapter tip with
mating
connector and 50
ohm terminations.
6-35.
The maximum input to the probe is
30V
rms
or
200V dc.
These voltage limits
may be used in
combination
so
that
the ac
component of an
ac
signal
superimposed on
dc level can be measured.
CAUTION
Changing the dc level of the input signal by
more
than 200
volts will damage
the
probe.

6-37.
Use the following procedure for
operating the
8600A with
the
80RF-1
probe:
a. Connect the 80RF-1 shielded
dual-banana
plug
to the 8600A
V-Sl
and LO
INPUT terminals.
b.
Attach
the desired
probe tip
to the probe
body.
c.
Depress the

pushbutton
(FUNCTION)
d.
Select the
20,
200,
or 1200V range.
NOTE
The probe loading error caused
by
the

input
impedqnce on the
8600A
200

ranges can
be corrected
by
placing a

resistor
across
the
dual-banana plug
terminals.
