Safety Read this manual in its entirety before operating the Model 101 Signal Conditioner. Read all wiring and power hookup instructions and understand the requirements prior to using another manufacturer's products with the Model 101. Insure that any product being interfaced with the Model 101 is wired according to prevailing local safety and operational standards before operating.
The Model 101 uses dual 12-bit DAC's, for each channel, to autozero the input and output amplifiers for DC input signals. Input signals with magnitudes of +/-10 Vdc can be zeroed. Unzeroing the amplifier zeroes both autozero DAC's.
No isolation channel to channel or signal ground to case ground Physical Characteristics Dimensions 8.25”w x 3.25”h x 9.25”d (210 x 83 x 235mm) Weight (w/o power cord) 3.4lbs (1.5kg) Case Material Iridited aluminum Operating Manual Model 101, Revision 1 Page 6 of 14...

CH1, CH2 and CH3 Output BNC Connector (50 ohm) Typical Hookup to Oscilloscope Note: The Model 101 Signal Ground is isolated from power ground. This allows connecting the oscilloscope Power Ground to the 101 Signal Ground. To minimize high frequency EMI susceptibility, install clamp-on ferrites with frequency bands of 80MHz to 800MHz.
