System Timer Overview
For internal operation, the 9530/8530 contains a timer and mode generator which generates an
internal
T
0
clock that is used to trigger all the channel timers. System modes are controlled via the
Mode menu.
Using Continuous Mode
The Run/Stop button starts and stops a continuous pulse stream at the rate specified by the Rate
menu. This corresponds to the normal output mode for most pulse generators. To generate a
continuous stream of pulses:

Within the System Mode menu select Continuous mode.

Within the Rate menu:
o Select the system oscillator or external clock in frequency.
o Set the desired frequency
Pressing the Run/Stop key will now generate a stream of T
0
pulses at a rate specified by the period
parameter.
Using Single Shot Mode
To generate a single pulse with every press of the Run/Stop key:

Within the System Mode menu select Single Shot mode.
Pressing the Run/Stop key will now generate one pulse.
Using System Burst Mode Function
The Run/Stop button generates a stream of ‘N’ T
0
pulses, where the ‘N’ is specified by the Burst
parameter. The rate is specified in the Rate menu. Pressing the Run/Stop button while in the burst
is in process will stop the output. After the burst has been completed, pressing the Run/Stop button
will generate another burst. To generate a burst of pulses set:

Within the System Mode menu:
o Select mode to be Burst
o Set the Burst parameter to produce the number of pulses desired
Using the System Duty Cycle Function
The Run/Stop button starts a continuous stream of T
0
pulses, which oscillates on for ‘N’ pulses and
off for ‘M’ pulses, where ‘N’ and ‘M’ are specified by the On/Off parameters respectively. The rate at
which the pulses are generated is controlled in the Rate menu. To generate a stream of pulses
which will oscillate on for ‘N’ pulses and off for ‘M’ pulses set:

Within the System Mode menu:
o Set the mode to Duty Cycle.
o
Set the On parameter to the number of pulses to produce during the on cycle (‘N’).
o Set the Off parameter to the number of pulses to suppress during the off cycle (‘M’).

Within the Rate menu:
o Set the Source to either the systems internal oscillator or to external mode.
