The DC 503 Universal Counter offers counting to 100 MHz and
provides the versatility of six measurement funcitons: frequency, period,
ratio, time A to B, time manual, and totalize. The two channels (A and B) have
individual BNC inputs and separate trigger level, attenuator, and coupling mode
controls. 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. A flashing display
indicates register overflow. The DC 503 offers high performance in a variety of
applications. Its interval measurement capability with selectable clock rates
is useful for digital equipment design and maintenance, particularly digital
control and data communications work. The A-channel frequency range of dc to
100 MHz serves in communication and rf use. High resolution measurements of low
frequencies are available quickly in the period mode with averaging up to 1
million periods available. TIME MANUAL provides an electronic stop watch
function with selectable clock rates. TOTALIZE counts and display the total
number of input events at rates from dc to 100 MHz.
