• Model 310H

The Model 310H is a 800V electrical plug in for the BNC Model 6040 Electro/Optic Pulse Generator Mainframe


Fast 800 V Pulses Into 50 Ohms

Model 310H adapts the Mainframe 6040 to amplitude requirements of up to 800V for 50 ohm loads. The operating capabilities of the 6040/310H provide outputs in the form of 1 ns resolution digital delays and gates and PRFs from .01 Hz to 100 kHz (or one shots), in both single and double pulse formats. Leading edge transitions are 10 ns or less and trailing edges as low as 10 ns. Polarity is switch selectable and pulse width can range from a minimum of 25 ns up to 20 us.

The 6040/310H combination retains the high timing accuracy, low jitter, nanosecond resolution, memory storage, and programmability available with other installed 6040 modules. Also, the 310H self-protects against damage from operation at excessive duty factors or into a short circuit, with a light signaling overload conditions. Refer to the eight-page Model 6040 product bulletin or at this site for additional detailed information on equipment operation, a timing diagram, and applications.

Common Module Specifications


ROM determines the instrument's allowable operating conditions and units of display applicable for the installed module.

A nonvolatile memory (RAM) in each module stores up to ten complete settings of operating conditions (trigger level, slope, etc.) and output pulse parameters.


The RAM-stored settings can be manually or bus transferred to the mainframe to produce the pre determined outputs.


2 Ibs net (0.9 kg); 5 Ibs shipping (2.3 kg).


Same as Model 6040 mainframe.
