Combining Parameters for Signal Generation

The following table shows you how the various modes and parameters

can be combined. Empty cells indicate that the combination is not

applicable:

NOTE For the clock source, the Internal YIG Oscillator, Exter nal Clock Input

and 10 MHz Reference can be used as the clock source for all

combinations. The Internal D irect and External Direct can only be

used as the clock source for Square pattern mode and NRZ signal

mode.

Instrument Modes

The instrument provides the following modes:

• Pulse/Pattern Mode

In this mode, each channel can be set independently to generate a

continuous stream of:

– Square waves (clocks) of fixed width

– Pulses with selectabl e width or duty cycle

Instrument Mode Pulse/Pattern Burst RBurst

Pattern Mode Square Pulse Data/PRBS Data Data

Signal Mode R1 RZ NRZ R1 RZ NRZ R1 RZ NRZ
