Position (Position)
Set the position of the selected marker.
You can move the markers within the range of −5 to 5 div of the frequency axis in 0.01 div steps.
Marker Shape (Marker Form)
Set the shape of the displayed marker to one of the options below.
• Mark: A dot
• Line: A
crosshair
Measurement Items (Item Setup)
Marker cursors move on the waveform data. You can measure the following values at the markers.
X1 Frequency at Marker1
X2 Frequency at Marker2
X3 Frequency at Marker3
X4 Frequency at Marker4
Δ(X2-X1) Frequency difference between Marker1 and Marker2
Δ(X3-X1) Frequency difference between Marker1 and Marker3
Δ(X4-X1) Frequency difference between Marker1 and Marker4
Δ(X3-X2) Frequency difference between Marker2 and Marker3
Δ(X4-X2) Frequency difference between Marker2 and Marker4
Δ(X4-X3) Frequency difference between Marker3 and Marker4
Y1 Level at Marker1
Y2 Level at Marker2
Y3 Level at Marker3
Y4 Level at Marker4
Δ(Y2-Y1) Level difference between Marker1 and Marker2
Δ(Y3-Y1) Level difference between Marker1 and Marker3
Δ(Y4-Y1) Level difference between Marker1 and Marker4
Δ(Y3-Y2) Level difference between Marker2 and Marker3
Δ(Y4-Y2) Level difference between Marker2 and Marker4
Δ(Y4-Y3) Level difference between Marker3 and Marker4
Peak Cursors (Peak)
In the frequency range defined by FFT1 Range1 and Range2 and the frequency range defined by FFT2 Range1
and Range 2, the DL850E/DL850EV detects peaks (Peak1 and Peak2
*
) and measures their frequencies and
levels. You can set the two frequency ranges in the range of −5 to 5 div.
* You can set this item on models equipped with the /G2 option.
Measurement Items (Item Setup)
The following values at the peaks are measured. F2 and Y2 are items that can be measured on models with the
/G2 option.
F1 Frequency at Peak1
F2 Frequency at Peak2
Y1 Level at Peak1
Y2 Level at Peak2
