Digital Assembly Description

3.3.1

Overview

Refer to the Digital PC block diagram in Figure 3-4, and the Digital Timing Diagrams in Figures
3-5, 3-6 and 3-7.

The digital board provides the timing functions for delays between a small negative time (with
respect to either the video monitor, or the sampled pulse) and >100 ms. In the CW mode, the
digital board is not reset, but continues to generate clocks and samples at about 70

µ

s

intervals. In either the INTernal or EXTernal modes, an acquisition is requested by the host (the
power meter to which the sensor is connected is the host) which causes READY to be set.
When an input trigger is received, it is latched and delayed by a FINE delay, and then starts a
10-MHz clock. The clock increments a COARSE counter until it reaches FFFFF or all ones, and
then outputs a Ripple Carry Out (RCO) signal. This is latched as SAMPle, delayed by one
count, and then compared to the count of 51

µ

s out of the counter to allow the SAMPle to be

51

µ

s wide. Then the COARSE counter is reLOADed for about 5

µ

s, the 10-MHz clock is

stopped for about 5

µ

s, the LOAD unasserted, and the TRIGger, SAMPle, and READY flip-flops

reset for about 1

µ

s. A 48-bit serial stream provides the 80350A configuration information. When

the serial clock is running, CLKHOLD resets the TRIG loop and loads the counter.
