POLAR GRAPHS

The polar graph is a convenient way to view magnitude and phase. The signal is represented as a vector on an X-Y coordinate axes. The full screen polar display is shown below. The split screen polar graph is half as big.

Plot of X and Y

The polar graph is not labelled - there is no trace identifier above it. This is because the polar graph always plots X and Y as a vector. This display cannot be changed to display any other traces. Changes made to X and Y, such as offsets, will change the vector on the polar graph. Changes made to R, such as offset, will not.

The [ACTIVE DISPLAY] key will not select this dis- play since there is no cursor associated with it and it cannot be autoscaled.

Scale

The graph is oriented like a normal X-Y axes. Positive X is to the right and positive Y is up, and zero is in the center. The four circles indicate 25%, 50%, 75% and 100% of full scale. The polar graph is always scaled to the full scale sensitivity. Note that X and Y can both be full scale in amplitude and the resultant vector exceed full scale by √2 (at 45°).

Signal Vector

Coherent signals have a steady phase and the signal vector will have a steady direction. Signals which are noisy will move around in direction as well as magnitude. The polar display can quickly give a feeling for whether a signal is coherent or not. Signals whose frequencies are close to, but not synchronous with the reference frequency will to rotate at the difference frequency between the signal and reference.

Offset and Expand

If the either X or Y has a non-zero offset or a non- unity expand, then the Offst and Expd alert indica- tors are turned on. The vector is plots the offset and expanded quantities X and Y. If X and Y have unequal expands (differing gains), the signal vector is generally not meaningful.
