Agilent / HP / Keysight 8010A
8010A PULSE GENERATOR
Description
The Agilent/HP 8010A is a dual channel pulse generator which has a repetition rate of 1 Hz to 10 MHz, which is extendable to 20 MHz in double pulse mode.
Individual switching of channels A and B permits the application of an external trigger to one channel while the other remains internally triggered.
Complete regulation of the pulse delay, width, rise and fall times, amplitude and dc offset can be achieved by front panel controls.
All the front panel controls of HP 8010 are calibrated with the exception of the dc offset.
In the parallel operation of the normal delay mode, both pulses are referenced to the trigger output, therefore, optional delay of either pulse can be obtained while the other remains fixed.
Hence, the output of channel A or B can be delayed from 50 ns to 1 s with respect to the trigger output.
In the series mode, combining A and B makes channel A the reference for channel B. Channel amplitudes are adjustable independently from 5 volts to 0.02 volts with consideration for the output impedance of 50 ohms, a seven step attenuator of HP 8010A reduces the output in a 5, 2.5 and 1 sequence.
A maximum of 10 volts output amplitude is readily available from channel B, by operation of a rear panel switch and the output combining switch.
The pulse parameters are consequently controlled through channel B. The 8010A pulse generator can be operated in a square wave mode.
Symmetrical, dc coupled, square waves from 1 Hz to 10 MHz with variable rise and fall times are available at both outputs.
