The Fluke Model 7261A is a bench-type, portable Universal Timer/Counter. A self check mode of operation is provided to verify overall instrument performance. The instrument can make four types of measurements: frequency, period of an input frequency, time interval between any two events with averaging functions, ratio measurements of one frequency to another, and totalized count measurements. Both Channel A and B have an input impedance of 1 MOhm. Both Channels have trigger status lights, ± slope selection, 3 position attenuator switches, AC/DC coupling select controls, 100 kHz low pass filter select switches, analog trigger level outputs and the capability of bein gelectrically connected together. A marker output is available when either the TI A-B or the TIA A-B function is selected. The optional Channel C has an input impedance of 50 Ohms and is ac-coupled. This channel is used for frequency measurements only and has no Front Panel controls.
