Refers to the frequency of a projector, monitor or signal. All computer signals 'scan' across the screen, building up the image. Expressed in Hertz (kHz).

Referring to the horizontal or vertical rates, expressed in Kilo Hertz(kHz).

The frequency in Hertz (Hz) at which the monitor is scanned horizontally. Generally, the higher the scan rate, the higher the resolution.

The frequency with which a video display device "paints" scan lines. NTSC video has a scan rate of 15,734 lines per second (525 lines per frame multiplied by 29.97 frames per second), or 15.734k Hz.

The rate at which a group of channels is sampled, measured from scan to scan. For example, if 10 channels are in a scan, and a sample rate of 1,000 samples per second is specified, the scan rate is 100 scans per second.

6.25 scans/second

Other names for execution interval.
