Page 2: Technical Overview
DC and AC currents flow through the cables and the modulator. Input Signal Requirements: The Model 25A is DC coupled. Care should be taken in matching the input signal levels to that described below and on the front panel. The front panel of the driver contains a peel-off label instructing the user which of three different types of inputs the system is configured to accept. - Page 3 “storage delays” may result. The amplifier may take hundreds of microseconds to recover. Do not attempt to increase the input level beyond 1.0v limit.

- Page 4 “clip” and it will affect the operating point of the E.O. modulator, causing “bounce” in the detected output. If the above input signal is DC coupled form the source, no precautions are necessary.
