Introduction
General Information
General Information
The Pulse G enerator gen erates all st andard pulses, digital pa tterns and
multi-level waveforms needed to t est all curre nt logic technologi es (e.g.:
TTL, CMOS, ECL, PECL, LVDS, GTL) and other digital designs up to
330 MHz. The HP 81 1 10A p rovides a reliabl e and wide range of signals,
which can be used in even more applications than its predecessor, the
HP 8110A. This is due to enhancements made in the feature set and
specifications of the HP 8110A. The glitch and drop out free varying of
any timing parameter and the HP 81110A’s timing calibration feature
contributes to more accurate and confident characterizations of the
DUTs.
Benchtop Testing
The graphic display shows all pulse parameters at a glance, the Cursor
keys and the Modify knob allow fast and simple operation. The HP
811 10A is equ ipped with the familiar Use r Interface f rom the HP 81 10A,
providing no learni ng curve for those already familiar with the predecessor product. The User Interface is designed to reduce/minimize the time
invested in getting familiar with the instrument. After familiarization the
instrument supports quick set ups of signals. This leaves the user free to
concentrate on the measurement task and testing of the DUT.
Automated Testing
The HP 81110A has the same SCPI conform command structure for the
feature sets identical to the HP 8110A. As with the HP 8110A, the new
product can be easily integrated into all phases of test-system development such as planning rack integration and test program generation.
These benefits along with the low cost of ownership make the
HP 81110A an invaluable instrument in a wide range of technical applications. Programs designed for the HP 81104A can be used without any
changes for the HP 81110A with HP 81111A 10V/165 MHz outputs.

Access the Operating/Trigger Mode (MODE/TRG) screen by pressing
the
|MODE/TRG| softkey. Move the Entry Focus with the cursor keys.
In this screen you set the fundamental operating and trigger modes with
respect to the signal required. For example, the operating mode for a
simple clock or pulse signal is the pulse stream (
Pulse Strm), PULSES
mode. Burst signals (several pulses and a pause) are easily set up in
BURST mode. Data streams (also PRBS’s) require the Pattern mode.
You can specify the pulse period source. If you have to trigger after an
external event then use the starta ble osci llator (internal Osc) which st arts
on the external signal with a fixed latency. If you do not have to trigger
but need a high accuracy freq uency, then use the interna l PLL cloc k generation circuitry. In triggered/gated mode the internal PLL can be used
as trigger sou rce.
In
Pattern mode you specify the data outp ut format in this screen, either
RZ or NRZ.
