Hewlett packard 8082A pulse generator
This is a FULLY functional pulse generator that has been well maintained and has had light use. See Specifications below:
HP 8082A 250 MHz Pulse Generator Specifications
Pulse Characteristics (50Ω source and load impedance)
1ns to 0.5ms in 6 ranges at amplitudes >1.8V and >4.5V respectively in the two upper output ranges. Minimum value may increase to 1.2ns at other amplitudes. Leading/trailing times are common on fastest range, and independently variable over 1:10 ratio on other ranges.
± 10% of pulse amplitude may increase to ± 10% with amplitude vernier CCW.
Linearity abberation for both slopes ± 5% for transition times > 5ns
Maximum amplitude is 5V from 50Ω into 50Ω. Maximum output voltage is ± 5V (amplitude + offset)
5% in ECL setting, increasing to 15% in 5V range.
Cannot be damaged by open or short circuits or application
Two separate three step-attenuators reduce the outputs to 1V. Vernier is common for both outputs and reduces the output to 0.4V minimum. A further position provides ECL-compatible outputs (-0.9V to -1.7V typ. open circuit).
2ns - 0.5ms in 6 ranges plus typ. 17ns fxd. with respect to trigger output. Duty cycle >50%
up to 125MHz max. (simulates 250MHz)
Delay and double pulse are disabled, max. Rep. Rate 250MHz. Duty cycle is 50% ± 10% up to 100MHz, 50% ± 15% for > 100MHz
Negative going Square Wave (50% duty cycle typ.) >500mV from 50Ω into 50Ω. Internal 50Ω can be switched off by slide-switch on PC-board. Amplitude up to 1V into 50Ω up to 200MHz
Cannot be damaged by short circuit or application of external ±200mA
Positive, negative or manual selectable. In the manual position all ext. functions can be controlled by push button. Button pushed in simulates an "on-signal."
Sine-wave >200mV p-p pulses >200mV
There is approximately 7ns delay between the external input and the trigger output. Rep. rate is externally controlled (is triggered by external signal). Trigger output provides the pulse-shaped input signal.
Gating signal turns rep. rate generator on. Last pulse normal width even if gate ends during pulse.
Output pulse width determined by width of drive input. Rep. rate and delay are disabled. Trigger output provides shaped input signal.
100/120/220/240 Vrms; + 5%, -10%; 48-440Hz. 85VA max.
133 mm H x 426 W x 345mm D (5.2" x 16.75" x 13.6").
