Fig. 2-5. Typical CH A and CH B Level Out voltage settings for various time interval measurements.
EVENTS A DURING B MODE
In the EVENTS A DURING B mode, the events applied
to Channel A are counted. The count is gated by the signal
applied to Channel B input. The accumulated total of
events A that arrived during the time signal B was
triggered is displayed in the readout. Refer to Fig. 2-6.

measurement like that shown in Fig. 2-6.
1. Apply the signal to be counted to Channel A. With
t h e F U N C T I O N s w i t c h a t F R E Q U E N C Y A , s e t
Channel A SLOPE switch to + SLOPE. Adjust the
LEVEL control for a stable display.
2. Apply the control signal to Channel B. With the
FUNCTION switch at PERIOD B, set Channel B
SLOPE switch to + SLOPE, Adjust the LEVEL
control for a stable display.
3. Set the FUNCTION switch to EVENTS A DURING B.
When the Channel B signal excursion occurs, Channel
B is triggered andthe gate opens, allowing the Channel A
pulses to be counted.
A v e r a g i n g . Averaging can be used to Increase the
accuracy and resolution of repetitive event per interval

measurement tends to approach the true value of the
number of events per interval.
RATlO MODE
The DC 503A may be used to measure the ratio of two
signals, where one signal is applied to Channel A input
and the other signal is applied to Channel B input.
