Performance Verification
ADA400A Differential Preamplifier
31
Equipment
Required One digitizing oscilloscope (item 1) to supply power to the ADA400A
One digital multimeter (item 3)
One BNC female to dual banana connector (item 5)
One coaxial cable (item 9)
1. Set digital multimeter to measure resistance.
2.
Connect banana-to-BNC adapter to digital multimeter.
NOTE
. To avoid an erroneous resistance measurement, make sure the 1 M
Ω
input
resistance jumpers are installed.
3. Set ADA400A ‘+’ input to DC .
4. Connect coaxial cable from ‘+’ input of ADA400A to the BNC-to-banana
adapter on the multimeter.
5.
Check input resistance = 1 M
Ω ±
2% (980 k
Ω
to
1.02
M
Ω ).
6. Remove coaxial cable from ADA400A ‘+’ input and connect it to the
‘--’ input.
7. Set the ADA400A ‘--’ input to DC .
8. Check input resistance = 1 M
Ω ±
2% (980 k
Ω
to
1.02
M
Ω ).
