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.
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. Refer to the Keysight Technologies website for instrument driver 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. 02 | Keysight | E1420B High-Performance VXI Universal Counter - Data Sheet
