Programmable Waveform Synthesizer

Information

The model 178 Programmable Waveform Synthesizer is a 1 µHz to 50 MHz multifunction sweep Synthesizer that can operate as a trigger, gate or burst Generator at levels to 20 volts peak-to-peak. It is synthesized to 8 digits in all modes. Its main Generator, an 8 digit 50 MHz Synthesizer, produces sine and square waves and, at reduced frequencies, triangles, ramps, pulses and haverwaves. An external reference input can phase lock the Synthesizer by locking the reference source. Phase locking allows the Synthesizer to operate as a variphase Generator with phase offset in 0.010 increments. The output level is specified into a 500 load from 1 mV to 20 Vp-p with 3 digits resolution, DC offset can be programmed to vary the waveform base line ±10V. Amplitude is displayed in units of Vp-p, Vrms or dBm for any waveform. The internal sweep Generator varies the main Generator frequency (lineariy or logarithmically) between the start and stop frequencies. The sweep Generator has its own operating modes: triggered, gated, hold at start and hold at stop. In addition, ten programmable frequency markers, available one at a time, can be used to indicate critical frequencies within the sweep. The sweep Generator can internally trigger the main Generator to produce pulses with a 10 ms to 10 min. repetition rate and 5 ^s to 5 days pulse width. Two external inputs may be used to phase- or ampiitude-modulate the Synthesizer, if the Synthesizer is phase modulated, the main Generator (when operating at frequencies above 500 kHz) varies up to ±360°. When amplitude modulated, the output can be modulated up to 200%. Data entry is from the front panel or GPIB with microprocessors controlling the data. Numeric input is entered in free format: fixed, floating or exponential notation. Parameters may be entered in any order. Internally, all entries are checked for errors and interactively displayed on the front panel. Up to 5 complete sets of programming may be stored and rapidly recalled. 1.2 OPTIONS Option 001 allows up to 40 sets of complete front panel settings to be stored in memory. Memory is battery backed up (internally recharged) for 60 days (minimum) retention of settings. Memory is expandable to 240 settings. Option 002 provides an additional high stability frequency reference crystal for greater accuracy. The high stability frequency has an accuracy of ±5 x 10_8 and an aging rate of 5 x 10~s/day (average) or <4 x 10~8/ week.
