Tektronix TEKFAX ADA400A Datasheet

Provides Low Level Signal
Acquisition Capability to DSOs
10 µV/div Sensitivity
Low Pass Filters for 100 Hz,
3 kHz, 100 kHz, and Full (1 MHz)
CMRR: > 100 dB DC to 10 kHz
Selectable Gain:
100, 10, 1, or 0.1
Accurately Measures Signals
As Small As 5 µV
Ideal for Medical Research,
Mechanical Testing, and
Medical Equipment Design
No Additional Power Supplies or
Cables Required When Used
with Oscilloscopes That Have a
TekProbe ™ BNC Connector
Interface
ow low level differen-
N
tial measurements
can be made on any Tek
scope. The ADA400A pre-
amplifier is perfect for low
frequency differential mea-
surements or low ampli-
tude, single ended mea-
surements with lots of
noise.
The ADA400A preamplifier
is designed for biophysical
research and mechanical
transducer, medical diag-
nostic, and imaging equip-
ment design, as well as
audio equipment design
applications.
