Description PROGRAMMABLE WAVEFORM SYNTHESIZER
Information
                                    The Model 157 is a precision source of selectable sine,
square, or triangle waveforms that are generated from 100
μΗz (2% hours per cycle) to 1 MHz in 10 ranges. Output
amplitudes are selectable from 1 millivolt to 10 volts,
peak-to-peak, into a 50-ohm load. This instrument
incorporates a voltage-controlled generator that may be
swept over a 1000:1 frequency ratio with a 0-volt to 5-volt
analog input for frequency modulation of the selected output
frequency.
Four modes of operation can be programmed with the
front-panel controls. Three modes of operation are
programmable from a remote source by static logic levels or
contact closures. Frequency, amplitude, and function also
are programmable from either the front-panel controls or a
remote source.
The instrument is packaged for mounting in a standard
19-inch rack or for operating on a test bench.
