Agilent 70004A Spectrum analyzer

The 70004A display has a removable custom hardkey panel, one-key assistance
in selecting MMS instrument controls and several advanced firmware features.
Four modular instruments can be displayed simultaneously.
Display keyboards (softkeys and hardkey panels) control one instrument
at a time. INSTR keys let you pass control from one instrument
to another with a single keystroke.
The 70004A sends displayed graphics to a high-pressure printer or plotter.
It also supports HP PaintJet printers, so you can have
full-color printed documentation of your test results.
The HP-HIL connector on the panel allows you to attach
an Agilent 46021A or 98203C HP-HIL keyboard.
This can be used to control the system panel or enter user headers
or chromatograph commands and small downloadable programs (DLPs).
