FLUKE 7220A Frequency Counter

The Fluke Model 7220A is a nine-digit portable, bench-type Counter that provides wide-range frequency measurement capability up to 1300 MHz. There are two input channels. The ac-coupled Channel A input allows frequency measurements from 10 Hz to 125 MHz with 1 Megaohm input impedance. The Channel B input allows prescaled frequency measurements of continuous wave or burst signals from 100 MHz to 1300 MHz with 50 ohm input impedance. Channel A signal conditioning includes a X10 fixed attenuator and a X10 variable attenuator. For low frequency measurements, a 100 kHz low pass filter may be selected. Four standard resolution settings and gate times may be selected that allow resolution in decade steps from 100 Hz to 0.1 Hz. Four standard resolution settings and gate times may be selected that allow resolution in decade steps form 100 Hz to 0.1 Hz. Four additional resolution settings (up to 0.0001 Hz) are available when the Resolution Multiplier Option-351 is installed.

*This is a Web introductory price for one calibration of the FLUKE 7220A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
