4530 Series RF Power Meter
Main Menu > Channel 1 | 2 > Snsr Data > GainConst
Displays a sensor information screen showing the linearity calibration table that is stored in the EEPROM of
the currently installed sensor (CW sensors only). The list shows each “range” (measurement segment), along
with an Upscale and Downscale coefficient for that range. CW sensors have 7 ranges, for a total of 14
coefficients. Voltage sensors add a midscale coefficient and an eighth range, for a total of 24 coefficients.
Remote Command:
TKSCWRG (SYSTem:LANGuage
must be set to
BOON
)
Main Menu > Channel 1 | 2 > Load Ref
Loads the current average power level as the ratiometric mode reference level, and switches the measurement
to ratiometric (relative) mode. The power level applied to the sensor is stored as the reference level, and all
power readings will be in dBr, relative to this level. Immediately after the reference is loaded, the display
should always indicate 0.000 dBr until the applied power changes.
Remote Command:
CALCulate[1|2]:REFerence:COLLect
Main Menu > Channel 1 | 2 > Ref Off
Disables ratiometric (reference) mode. The measurement will revert to a normal, absolute (non-ratiometric)
power measurement mode. The stored reference level is, however, preserved, and it is possible to enter
ratiometric mode without reloading the reference by using the
Channel > Display > DispSrc
menu item to
set the display source to “Snsr1 / Ref1”.
Remote Command:
CALCulate[1|2]:REFerence:STATe OFF
Main Menu > Channel 1 | 2 > Enter Ref
Enters a ratiometric reference level from the keyboard, and switches the measurement to ratiometric (relative)
mode. The power level entered is always in dBm, and the arrow keys are used to edit the value. All power
readings will be in dBr, relative to this level.
Remote Command:
CALCulate[1|2]:REFerence:DATA <n>
3.11.3 Markers Menu.
The Markers menu is used to configure and locate measurement markers (cursors) at specific points on the
processed measurement waveform. Markers are used in Pulse mode to perform measurements at or between
two time offsets relative to the trigger, and in Statistical mode to measure the power at a particular statistical
percent, or the percent at a specified power level. In Pulse mode, the markers can only be placed on the visible
portion of the trace (as defined by the timespan and trigger delay settings), while Statistical mode markers may
be placed at any power or percent value and will still return readings.
Main Menu > Markers > Mrkr Mode
Selects the global marker orientation for the pulse and statistical modes. Markers 1 and 2 are always paired
and operate together. Markers are not used in the CW and modulated modes.
Off
Markers are not displayed, and no marker measurements are performed.
Vertical
Vertical markers appear as vertical bars on the graph display, and measure the
power at a particular time (Pulse mode) or percent (Statistical mode). (default)
