GETPLOT Get Plot<br />

Description<br />

The GETPLOT comm<strong>and</strong> transfers the trace data, graticule, <strong>and</strong> annotation of the spectrum<br />

analyzer screen to a plotter via the spectrum analyzer interface (softkey labels excluded). The<br />

data is transferred in ASCII, <strong>HP</strong>GL format.<br />

Before executing the downloadable program that contains GETPLOT, you should do one of the<br />

following:<br />

� Disconnect the computer from the spectrum analyzer.<br />

Or,<br />

� Send the following BASIC comm<strong>and</strong>s:<br />

ABORT 7<br />

LOCAL 7<br />

ABORT 7 instructs the computer to release control of the <strong>HP</strong>-IB, <strong>and</strong> LOCAL 7 allows you to<br />

control the spectrum analyzer from the front panel.<br />

When using the PLOT comm<strong>and</strong>, the scaling points (Plx, Ply; P2x, P2y) can be specified.<br />

These scaling points specify the (x,y) coordinates, which determine the size of the plot.<br />

(Plx,Ply) refers to the lower-left plotter coordinates. (P2x,P2y) refers to the upper-right<br />

plotter coordinates.<br />

Note The <strong>HP</strong> 7470A plotter does not support 2 plots per page. If you use an<br />

<strong>HP</strong> 7470A plotter with an <strong>HP</strong> <strong>8590</strong> <strong>Series</strong> spectrum analyzer, you can select one<br />

plot per page or four plots per page but not 2 plots per page.<br />
