Description
The Keysight Technologies, Inc. E1420B High-Performance Uni-
versal Counter is a C-size, 1-slot, message-based VXI module.
It provides the full set of traditional universal counter measure-
ments (frequency, period, time interval, totalize, and ratio),
plus the automatic measurements of rise/fall time, pulse width,
phase, and AC/DC voltages. Additionally, this module provides
xlO attenuation, allowing measurements of higher-powered
signals.
The E1420B is ideal for today’s ATE applications requiring high
speed in all phases of a measurement - setup, measure, and
output. It can make up to 60 measurements per second of the
same function. It can also sequence through a series of different
functions at up to 40 measurements per second. For even faster
measurements, the optional shared memory capability yields
up to 160 measurements per second. This shared RAM option
allows the El420B to send measurement data to a VXI device
with shared RAM. Data may be accessed by the controller, thus
eliminating data formatting time and providing higher measure-
ment throughput.
The El420B features the industry standard SCPI interface lan-
guage. SCPI will let you develop code that can easily be lever-
aged, increase the life of test software, and decrease the time
spent learning new instrument languages.

availability and downloading instructions, as well as for recent
product updates, if applicable.
Outstanding Resolution and Range
The E1420B offers a 200 MHz frequency range (2.5 GHz with
option 030) and 2 ns time interval resolution (200 ps with aver-
aging). Rise and fall times can be measured automatically down
to 15 ns.
Improve the System Clock Without Sacrificing
Mainframe Space
An optional highly stable TCXO time-base is available for the
E1420B. By externally driving the VXI system clock (CLK10) with
this TCXO, you can substantially reduce system clock errors
without losing valuable mainframe slots. This option improves
measurement repeatability and accuracy.
Measurement Timing Control
For synchronizing your measurement to an external event, such
as an RF burst, VXI bus and external triggering are available.
Programmable measurement time-outs help you optimize
system performance even if the input signal is absent.
Single Measurement Auto-Trigger Speeds
Measurements
Repetitive auto-trigger measurements are faster than ever with
the E1420B’s single measurement auto-trigger. This feature ana-
lyzes the input signal only once, setting the trigger levels, and
speeding through the rest of the measurements.
Adjustable Sensitivity
Measuring low-level signals isn’t a problem: the Keysight E1420B
features 35 mV rms sensitivity to 200 MHz. When noise is a
problem, this sensitivity can be decreased to 100 mV rms by us-
ing hysteresis control.
Optional 2.5 GHz Channel (Input 3)
Increase your frequency range to 2.5 GHz for communications
and navigation applications.
Save on Software Costs with SCPI
The E1420B features the industry standard SCPI interface lan-
guage. SCPI will let you develop code that can easily be lever-
aged, increase the life of test software , and decrease the time
spent learning new instrument languages. SCPI also simplifies
the use of the counter; for example, you can set a trigger level
using a percentage of signal amplitude.
