Determining the Effective Volts/Division

Description
Upper Bandwidth Selector. The Upper Bandwidth Selector reduces electrical
interference by limiting the frequency response of the amplifier to FULL (1 MHz),
100 kHz, 3 kHz, or 100 Hz.
Output Connector. The output connector contains connections for the TEKPROBE
interface and signal output.
If your oscilloscope cannot read the scale factor information, see Table 3 to
determine the effective volts/division setting. The effective volts per division is
the volts per division setting of the oscilloscope divided by the gain setting of
the ADA400A Differential Preamplifier. For example, if the volts/division
setting on the oscilloscope is 500 mV/division and the gain setting is 10, the
effective volts/division is 500 divided by 10 or 50 mV.
