E1420B HP Frequency Counter

The E1420B is a Frequency Counter from HP. When an engineer needs a piece of electronic test equipment that will accurately measure frequency, he or she uses a frequency counter. Frequency counters measure a repetitive electronic signal’s oscillations per second. This tool uses a frequency counter, which analyzes the number of oscillations or pulses in a specific time. There are frequency counters designed for radio and microwave frequencies, depending on the application.

 Additional Features:

  • 1-Slot, C-Size, message based
  • 200 MHz frequency range, optional 2.5 GHz channel
  • 9-digit resolution in 1 second gate time
  • 2 ns time interval resolution (200 ps with averaging)
  • Shared memory option configuration
  • Phase measurement and measurement timeout

The  Agilent E1420B provides the full set of traditional universal counter measurements (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 x10 attenuation, allowing measurements of higher-powered signals. The Agilent E1420B is ideal for 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 Agilent E1420B 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 measurement throughput. The Agilent E1420B features the industry standard SCPI interface language. SCPI will let you develop code that can easily be leveraged, increase the life of test software, and decrease the time spent learning new instrument languages.
