PLOTTER OUTPUT
GENERAL DESCRIPTION
This chapter describes the procedure for executing the PLOTTER OUTPUT function, and provides information for preventing problems that may arise while attempting to execute it.
EXECUTING PLOTTER OUTPUT
Connect an HP plotter via HP-IB to the spectrum analyzer:
Set the HP-IB address on the plotter to address 5:
16 8 4 2 1
4+1=5
ADDRESS
If the address switch on the plotter cannot be located, refer to the plotter’s operation manual.
LOWER
LEFT
Press the lower left recorder key 0 to execute the
PLOTTER OUTPUT function.

The function plots everything that is displayed on the CRT If desired, traces A, B, and C, the annotation and the graticule can be individually blanked from the CRT using front-panel functions (refer to Chapters 5 and 11).

PLOTTER PENS
You can also blank the HP logo from the display. To do this from a computer, execute:
OUTPUT 718; “DA 2174; DW 32;32;”
Or, to execute it from the front panel, press:
PLO-lTER O U T P U T
PLOTTER PENS
Traces A, B, and C, and the annotation and graticule are individually plotted with four different pens, provided there are four pen locations in the plotter. Pens 1, 2, and 4 plot traces A, B, and C, respectively, and pen 3 plots the annotation and graticule. For a two-pen plotter, pens 1 and 2 take the place of pens 3 and 4, respectively.
NOTE
There are certain types of equipment that prevent the PLOTTER OUTPUT function from being executed correctly. They are discussed in the next two sections.
CONTROLLER
The analyzer should not be connected via HP-IB to an active controller while attempting to execute the PLOTTER
OUTPUT function from the front panel. This is because the analyzer will abort any attempts to execute the function from the front panel when an active controller is on the bus.
PLOTTER
The 7245A/B, 7240A, 9872C, and 7550 Graphics Plotters work readily for executing the PLOTTER OUTPUT function. However, the HP 757OA, 7585, 7470A, and 7475A plotters require special operating instructions. The
HP 7570 and 7585 plotters work only in EMULATE MODE. For more information on EMULATE MODE, refer to the plotter’s operating manual. On the HP 7470A plotter, set the US/A4 rocker switch to the US position. For the
HP 7475 plotter, the US/MET and A4/A3 rocker switches must be set to the US and A4 positions.
