Agilent / HP 8082A
250 MHz Pulse Generator Specifications

Pulse Characteristics (50Ω source and load impedance)
Transition times (10% to 90%)	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.
Overshoot and ringing	± 10% of pulse amplitude may increase to ± 10% with amplitude vernier CCW.
Preshoot	± 5% of pulse amplitude.
Linearity	Linearity abberation for both slopes ± 5% for transition times > 5ns
Output	Maximum amplitude is 5V from 50Ω into 50Ω. Maximum output voltage is ± 5V (amplitude + offset)
Offset	±2V, into 50Ω
DC-source impedance	50Ω + 5% - 10%.
Reflection coefficient	5% in ECL setting, increasing to 15% in 5V range.
Output protection	Cannot be damaged by open or short circuits or application
Attenuator	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).
Timing
Repetition rate	250MHz to 1kHz in 6 ranges
Period jitter	<0.1% of setting + 50ps
Delay	2ns - 0.5ms in 6 ranges plus typ. 17ns fxd. with respect to trigger output. Duty cycle >50%
Delay jitter	<0.1% of setting + 50ps
Double pulse	up to 125MHz max. (simulates 250MHz)
Pulse width	2.4ns to 0.5ms in 6 ranges
Width jitter	<0.1% of setting + 50ps
Width duty cycle	>50%
Square wave	Delay and double pulse are disabled, max. Rep. Rate 250MHz. Duty cycle is 50% ± 10% up to 100MHz, 50% ± 15% for > 100MHz
Trigger output	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
Trigger output protection	Cannot be damaged by short circuit or application of external ±200mA
External Operating Modes
External Input
Input impedance	50Ω ±10%. dc coupled.
Maximum input	± 6V
Trigger level	Adjustable -1.5V to + 1.5V.
Slope control	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."
Sensitivity	Sine-wave >200mV p-p pulses >200mV
Repetition rate	0 to 250MHz.
External-Controlled Modes
External trigger	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.
Synchronous gating	Gating signal turns rep. rate generator on. Last pulse normal width even if gate ends during pulse.
External width	Output pulse width determined by width of drive input. Rep. rate and delay are disabled. Trigger output provides shaped input signal.
General
Operating temperature	0°C to 55°C.
Power	100/120/220/240 Vrms; + 5%, -10%; 48-440Hz. 85VA max.
Weight	net, 7.9kg (17.44lb). Shipping 8.9kg (19.63 lb).
Size	133 mm H x 426 W x 345mm D (5.2" x 16.75" x 13.6").
