3.3.13 MEAS Key (Measurement)
This section describes the menu displayed when the
MEAS
key is pressed.
Noise/Hz Displays the Noise/Hz menu, and allows you to set the frequency
width for noise measurement.
dBm/Hz Sets the vertical axis unit to dBm, and sets the marker readout sig-
nal level unit to dBm/Hz. In addition, the detector is automatically
set to the sample detection mode.
dBµV/ √Hz Sets the vertical axis unit to dBµV, and sets the marker readout
signal level unit to dBµV /√Hz. In addition, the detector is auto-
matically set to the sample detection mode.
dBc/Hz Sets the unit of delta marker signal level to dBc/Hz and turns the
marker fixed function (delta marker) ON, then sets the detector to
the sample detection mode.
Noise/Hz OFF Turns off the noise measurement mode, and displays the Measure
menu.
XdB Down Displays the XdB Down menu.
XdB Down Moves the normal marker to an intersection point on the trace x
dB down from the present location according to the MKR Read
DLT/LFT/RHT setting.
XdB Left Moves the normal marker to the left to an intersection point on the
trace x dB down from the present location.
XdB Right Moves the normal marker to the right to an intersection point on
the trace x dB down from the present location.
MKR Read DLT/LFT/RHT Selects the marker display under the x dB down function to either
DLT, LFT or RHT.
DLT: The delta marker is displayed on the left; and the nor-
mal marker, on the right.
LFT: The normal marker is displayed on the left.
RHT: The normal marker is displayed on the right.
Cont Down ON/OFF Toggles the count down function on or off.
ON: Sets the x dB down function to repeat continuously.
Establishes the trace peak point for each sweep which
is used as the reference point of the marker down.
OFF: Turns off the count down function.
