9057/9059
Equipment Required:
(a)
Signal Generator and 50 ohm pad.
(b)
Electronic Voltmeter.
(c)
15pF Capacitor.
Procedure
(1)
On the 9057 (or 9059 Channel 'A') set the Sensitivity Switch to 0.01 -lOY.
(2)
Connect the signal generator to the input of the electronic voltmeter with
a 15pF capacitor shunting the 50 ohm input of the voltmeter this simulates
the instrument input conditions.
(3)
Set the signal generator output to exactly 1 OmV on the voltmeter. Note
the exact reading on the signal generator control.
(4)
Connect the signal generator via the BNC 'T' piece with the 50 ohm load
to the input socket of the 9057 or (9059 Channel 'A').
(5)
Set the 9057/9059 Function Switch to FREQUENCY or FREQUENCY 'A'.
(6)
Set the signal generator frequency and the 9057 Push Button Range Switch
to the settings listed in Table
3.
Check that in each instance a stable and
accurate display is obtained.
