Programmable Pulse Generator - Hewlett Packard 8112A Compatible

GP1612H Series – Programmable Pulse Generator – HP 8112A Compatible

Programmable Pulse Generator - Hewlett Packard 8112A Compatible
  • 50MHz frequency range with 16Vp-p into 50Ω
  • Variable width and delay with variable transitions
  • IEEE 488.2 and SCPI compatible
  • Fully compatible with the Hewlett Packard 8112A Pulse Generator


The GP1612H features variable pulse widths from 10 ns to 10 s, delays from 0 ns to10 s with up to 6 digits resolution and adjustable output levels from –8V to +8V, with pulse amplitudes from .1V to 16Vp-p into 50 ohms load (.2V to 32Vp-p into open circuit). The Pulse Generator also features selectable complementary pulse and double pulse, in continuous, triggered, gated and counted burst modes. The GP1612H allows selection of predefined amplitude and offset for critical stimulus and testing of major semiconductor technologies as TTL, CMOS and ECL.


The GP1612H has been designed to replace the HP8112A Pulse Generator and as such, is compatible with all of the HP 8112A functions and is 100% compatible in its GPIB command set. The GP1612H can replace the obsolete HP8112A in existing test and measurement systems.

Variable Transitions
To make operation flexible, variable transitions (rise and fall times) can be programmed from 5 ns to 100 ms. With the flexible transition times, various shapes of pulses can be obtained for applications where parameters such as linearity, switching times or reflection times must be analyzed. Operational amplifiers slew rate can be measured or thresholds of devices and circuits can be easily tested using programmable rise and fall times.
Fast and Easy Operation
To make operation easy, GP1612H interface with the operator in a straightforward manner by which the front panel display always shows the parameter being varied and its value. If a new parameter just entered is not compatible with the existing setup status, the operator is informed by an error message. Test setups, up to 99 locations, can be stored and recalled. This feature allows simple test sequence development as well as no need for a controller in repetitive tests, with reduced bus traffic in ATE applications. Last user setup is also retained at power down.

Pulse Functions
Single One pulse at each selected period up to 50MHz repetition rate
Double One pair of pulses at each period up to 25MHz repetition rate. Both pulses have the same selected width; the position of the second pulse set by the delay control.
Operating Modes
Continuous Output continuous at programmed period rate.
Triggered Output quiescent until triggered by an internal, external, GPIB or manual trigger, then generates one cycle at programmed period rate.
Gated Same as triggered mode except pulses are output for the duration of the gated signal. The last cycle started is completed
Burst Same as triggered mode for programmed number of cycles from 2 to 999,999 as set by the N-BURST function
