Operation and Programming
EXAMPLE 4. RISE/FALL TIME AND SLEW RATE
In this example,step0 setsthe5335Afor Rise Time(in,fu10). After apause of 3seconds in stepl,
(this pause is recommended for allowing the Auto trigger circuitry to settle down), step 2 will
force the counter to read into simple variable A. Step 3 sets up the 9825A for a given floating
format. In step 4, the 9825A will display: “RISE TIME =-s.", showing the contents of simple
register A. The controller sets upthecounter for Positive Slew Rate A (full) in step6,and in step 7,
the 5335A reads into simple variable B. in step 8 the controller will display: “POS. SLEW RATE =
_V/$" showing the contents of variable B. The controller sets up the counter for Fall Time
(fulO asl) and waits for 3 seconds in steps 9 and 10. in step 11, the information from the 5335A is
read into simple variable A. The controller will display: "FALL TIME =-s.” and the contents
of variable A in step 12. The 5335A is set up for a Negative Slew Rate A in step 14, and the controller
reads this information into variable B in step 15; then the 9825A will show the contents of B along
with the display: "NEG. SLEW RATE =
_V/S” in
step 16, after which the whole process is
repeated.
