4530 Series RF Power Meter Operation
ESC/Stop Key 7 Aborts any operation in progress when in Menu Mode or Zero/Cal Mode.
Pressing ESC/Stop while running in Text Mode or Graph Mode first causes
the measurement process to stop. Pressing it when already stopped will
clear the screen and reset all measurement values. Pressing ESC/Stop
when the instrument is in remote mode (the GPIB has control of the
instrument and keyboard entry is disabled) will return it to local mode
(the instrument is under keyboard control) unless the local lockout com-
mand, LLO, has been issued by the controller.
Zero/CAL Key 8 Places the instrument in Sensor Zero/Calibration Mode and displays a
menu to allow automatic sensor offset and gain adjustments using the
built-in 50MHz calibrator or an external calibrator.
Text Key 9 Places the instrument in Text Mode to display the current measurements
in a numeric format. Pressing Text while already in Text Mode toggles the
top portion of the display between the normal Text Mode header and Edit
Mode for each active channel.
Graph Key 10 Places the instrument in Graph Mode to display the current measurement
waveforms in a graphical format. Pressing Graph while already in Graph
Mode toggles the top portion (header) of the display between the normal
Graph Mode header and Edit Mode for the active channel.
Menu Key 11 Places the instrument in Menu Mode to allow navigation of the menu
structure. Pressing Menu while already in Menu Mode returns the user
to the top-level Main Menu.
Sensor 1 - 2 12 One or two sensor inputs are located on the front, or optionally on the
rear panel of the instrument. These are 10-pin precision connectors de-
signed to accept only Boonton Peak or CW power sensors and Boonton
voltage sensors. The sensor inputs are not measurement terminals and
cannot be used for other than the intended purpose.
CAUTION
Do not attempt to connect anything other than a
Boonton sensor or sensor adapter to the Sensor inputs!
GPIB 13 A rear-panel 24-pin GPIB (IEEE-488) connector is available for connect-
ing the power meter to the remote control General Purpose Instrument
Bus. GPIB parameters can be configured through the menu.
