Showing Results for Keysight Technologies (Agilent HP) 8082A

The 8082A is a 250 MHz dual channel pulse source with variable leading and trailing edge transition times as fast as 1 ns. It also has variable pulse frequency, delay, width, offset, and amplitude. The normal/complement relationship and the polarity of either output can be reversed. Single pulse, double pulse, and square wave operations are available. There are also four trigger modes:

• Normal Mode: The 8082A operates as a self-contained pulse source with full control of the pulse parameters from the front panel controls
• External Trigger Mode: The pulse and trigger output frequencies are determined by the frequency of an externally applied signal. The other pulse parameters are varied from the front panel controls
• Gate Mode: A gating signal enables the pulse and trigger outputs
• External Width Mode: The pulse frequency and width are determined by the frequency and width of an externally applied signal. The delay between the input and output is fixed. The trigger output is the shaped trigger input signal

The 8082A has an ECL position on each of its amplitude range switches. When either or both of the switches are set to this position, both 8082A outputs automatically deliver a fixed voltage swing of -0.9 V to -1.7 V typical (into an open circuit) for driving ECL logic.

• Transition times: ≤1 ns to 0.5 ms in 6 ranges
• Overshoot and ringing: ≤±6 % of pulse amplitude
• Preshoot: ≤±5 % of pulse amplitude
• Linearity aberration: ≤5 % for transition times >5 ns for both slopes
• Maximum output: ±5 V
• Offset: >±2 V
• Baseline: 0 V ±150 mV with offset switched off and amplitude range set to maximum
• DC source impedance: 50 Ω
• Reflection coefficient: Typically 2 % for steps with 1 ns rise time applied to output connector on all amplitude ranges except 5 V range. On the 5 V range, the relection may be 15 %
• Output protection: Cannot be damaged by open or short circuits or application of external signals ≤±6 V or ±200 mA
• Attenuator: Two separate three step attenuators reduce the outputs to 1 V. Vernier is common for both outputs and reduces the output to 0.4 V minimum. A further position provides ECL-compatible outputs
• Repetition rate: >250 MHz to <1 kHz in 6 ranges
• Period jitter: <0.1 % + 50 ps
• Delay: <2 ns to >0.5 ms in 6 ranges
• Delay jitter: <0.1 % + 50 ps
• Double pulse: Up to 125 MHz max
• Maximum variable delay time: 50 % of period - 2 ns
• Pulse width: <2.3 ns min to >0.5 ms max
• Width jitter: < 0.1 % + 50 ps
• Maximum width duty cycle: >50 %
• Square wave: A further position of the Pulse Width switch provides square wave output (delay and double pulse are disabled)
• External input impedance: 50 Ω
• Maximum external input: ±6 V
• Trigger level: Adjustable -1.5 V to +1.5 V
• Slope control: Positive, negative, or manual selectable
• Sensitivity: Sine wave >200 mVp-p, pulses >200 mV
• Repetition rate of external operation: 0 to >250 MHz
• Externally controlled modes:
  • External trigger - Repetition rate is determined by the external trigger signal. Trigger output delay is typically 7 ns. Square wave mode is disabled
  • Synchronous gating - Rate generator starts with a half period delay. Last pulse is of normal width even if gate ends during the pulse
  • External width - Output pulse width is determined by the width of the drive input. The repetition rate and delay are disabled
