Tektronix DC503
Universal Counter Plug In 100MHz
Description
This Counter has two input channels, A and B, each with 125MHz capability.
Each channel has separate triggering level, triggering slope, attenuator, and coupling mode controls.
Signals to be counted or timed can be applied to channels A and B via front panel BNC connectors or through rear interface connections.
This unit offers counting to 100MHz and provides the versatility of six measurement funcitons: frequency, period, ratio, time A to B, time manual, and totalize.
Seven digit readout is via seven segment light emitting diodes (LEDs) with automatically positioned decimal point; leading zeros (to the left of the most significant digit or decimal point) are blanked.
