Calibration—P6047
SECTION
4
CALIBRATION
The P6047
has been designed for
use with
instruments having an input impedance of
1
megohm
paralleled
by
15
to
20
picofarads,
and
is
factory-calibrated for
20
picofarads.
The
high
frequency response of the probe should
be checked periodically, or when changing from
one oscilloscope input
capacitance
to another.
Equipment Required
1.
Fast-rise
Test
Oscilloscope with sweep rate
of
0.1
,usec/cm and
10X
magnification,
such
as Tektronix Type 454 or Type
647A
with
10A2A
and
1132A
plug-in
units.
2.
500
Pulse
Generator
(Tektronix
Type
109).
3. 60

Line (Tektronix
Type
113
Delay Cable).
4. Two
509
Coaxial Cables—5 nanosecond
lengths of RG-8A/U
with GR
connectors.
(017-
0502-00).
5.
GR-to-BNC
Adapter
(017-0063-00).
6.
509
BNC
Termination
(011-0049-00).
7.
BNC-to-Probe
Adapter
(013-0084-00).
8.
Reactance Meter
(Tektronix
Type
130).
9.
Constant Amplitude Signal
Generator
(Tek-
tronix Type
191).
10.
509
Coaxial Cable—with
BNC
connectors
(012-0057-00).
NOTE
Before completing the high-frequency
calibration, adiust
C9
(low-frequency
compensation capacitor) as described
in
Section 2.
