Operation 4530 Series RF Power Meter
Main Menu > Utilities > Recorder > Calibrate > Slope Adj
Adjusts the slope, or gain of the recorder output. This command is typically used with a recorder Zero Adj
command to calibrate the recorder output for maximum absolute accuracy. The setting represents the devia-
tion in percent from the factory default slope value, and may be adjusted in 0.01% increments, corresponding
to 1mV at fullscale, although actual output resolution is 5mV. Changing the slope “pivots” the curve around
the 0.0 volt setting, and will have maximum effect at -10.0 volts and +10.0 volts. Note that this setting is not
permanent unless “Save Cal” is used.
Range: -10.00 to +10.00% (corresponds to actual slope of 90.00 to 110.00% of default)
Remote Command: OUTput:RECOrder:CALibration:SLOPe <n>
Main Menu > Utilities > Recorder > Calibrate > Zero Adj
Adjusts the zero, or voltage offset of the recorder output. This command is typically used with a recorder
Slope Adj command to calibrate the recorder output for maximum absolute accuracy. The setting increases or
decreases the actual output voltage by a fixed amount, and may be adjusted in 1mV increments, although
actual output resolution is 5mV. Changing the offset moves the entire curve up or down, and has equal effect
at all output levels. Note that this setting is not permanent unless “Save Cal” is used.
Range: -1.000 to +1.000V
Remote Command: OUTput:RECOrder:CALibration:ZERO <n>
Main Menu > Utilities > Recorder > Calibrate > Save Cal
Saves the recorder Zero and Slope adjustments to the instrument’s non-volatile calibration memory once they
have been set. If this step is not performed, the settings will revert back to the previous settings next time
instrument power is applied.
Remote Command: OUTput:RECOrder:CALibration:SAVE <n>
Main Menu > Utilities > Sys-Tests > SystemInf
Display a set of information screens showing system information. Info includes: serial number, model number,
internal firmware versions, calibration information, accumulated hours, power cycles, memory checksums,
and sensor calibration settings. The information will be on two or more pages, and the
∧ and ∨ keys may be
used to scroll back and forth.
Main Menu > Utilities > Sys-Tests > Voltages
Display an of information screen showing internal system voltages and current sensor temperature. Pressing
the
∧ and ∨ keys may be used to scroll back and forth between the measured values, and the raw A/D counts.
Main Menu > Utilities > Sys-Tests > Disp Test
Perform a diagnostic test on the LCD display. The screen will first set and clear all pixels by wiping across,
then will display the full character set of each of the internal fonts. Note that if the display appears too light
or dark, the contrast may be adjusted by holding down the ESC key while pressing the
∧∧∧∧∧ ∨∨∨∨
or
∨ keys.
Main Menu > Utilities > Sys-Tests > Keypad
Perform a diagnostic test of the front panel keypad. Pressing any key should highlight the symbol for that key,
and pressing it multiple times should cause the count to increment each time. To test the full keypad, press
each key at least once. Press the ESC key last, as this key terminates the test.
