Setting Pulse Output Parameters

There are two basic types of outputs available on the 9530:

a) TTL/CMOS compatible outputs.

b) Adjustable amplitude outputs.

Out:

Selects between TTL/CMOS mode and Adjustable

mode when both are available on a single output.

Pol:

Sets the voltage polarity of the pulse, active high or

active low.

*Note: All outputs are positive voltage as negative

voltages are not supported

Ampl:

In Adjustable mode the unloaded output voltage is set.

The actual output voltage will depend on the load

impedance. For example: If the load is 50Ω the output

will be 50% of the stated voltage.

Using the Output Multiplexer

Each output channel includes a multiplexer which allows routing of any or all of the timer outputs to

the physical output. This allows double pulses and other complex pulse trains to be generated.

The multiplexer is represented by an “n” bit binary number as shown above. “N” is the number of

channels. Each bit represents a channel timer, which is enabled by setting the bit to one. In the

above example, timers A and C are combined on the current output.

Setting System Internal Rate Parameters

The internal T

period controls the fundamental output frequency of the system. Each channel may

be operated at submultiples of the fundamental frequency by using the channel duty cycle mode.

Source:

Sets the reference source for the internal T

period.

Per:

Sets the internal T

period.

To set the system Internal Rate press the Menu key, then use the arrow keys

to specify the T

period.
