Tektronix DC503A Universal Counter/Timer
The DC 503A Universal
Counter/Timer is designed to operate in a TM 500-series power module.
The instrument has two input
channels, CH A and CH B, each with 125 MHz capability. Each channel has
separate triggering level, triggering slope, attenuator, and coupling mode
controls.
The DC 503A has eight
measurement functions: FREQUENCY A, PERIOD B, WIDTH B, TIME A-B, RATIO A/B,
EVENTS A DURING B, TOTALIZE A, and TIME MANUAL. All of the modes except
FREQUENCY A, TOTALIZE A, and TIME MANUAL have the capability of averaging the
selected measurement over a range of 1 to 10(exp 8) times the input signal. The
signals to be counted or measured can be applied via front panel bnc connectors
or throught the rear interface.
The triggering level for each channel can be monitored via
the front panel or the rear interface connections. The buffered voltage
available at these connectors corresponds to the trigger levels set by the
front panel controls.
The output of the internal
signal shaping ciruits can also be monitored via front panel connectors. These
shaped signal outputs are useful in setting the triggering points on complex
waveforms.
Measurement results are
displayed in an eight digit LED readout. The decimal point is automatically
positioned and leading zeros are blanked. Single annunciators (LEDs) are used
to indicate register overflow, active gating interval, and the frequency or
time units associated with the measurement being made.
The DC 503A can be equipped with an optional, oven
controlled, 10 MHz crystal oscillator to obtain a highly stable and precise
internal time base. Both the optional oscillator and the standard 10 MHz time
bases provide 100 ns single shot resolution.- 制造商: Tektronix
