Operation and Programming
EXAMPLE 5. DUTY CYCLE
This program will set up the 5335A for a Duty Cycle measurement (positive portion of waveform,
in fu12) in step 0; then, in step 2, forces the counter to read into simple variable A. Step 3 displays
the contents of variable A, format: “ 'UP' Duty Cycle =_ %” and maintains the display for 3
seconds (step 4). In step 5, the 5335A is programmed for a Duty Cycle measurement of the
negative portion of the wave form (asl) and in step 7, the 9825A will display: "'DOWN' Duty
Cycle =- %”; after waiting for 3 seconds, the total cycle is repeated.
