Each frequency when start / stop is specified is displayed.
The marker position for each trace is displayed. The selected marker can be moved in the following ways.
- Drag a marker on the touch panel
- Long press the lever switch
4. Calibration status
Displays the data number of the calibration being read and the error correction applied.
C4: Each indicates that the corresponding calibration data is loaded.
c4: Each indicates that the corresponding number of calibration data is loaded, but the frequency range has been changed after loading, indicating that the error correction is using complement.
D: Indicates that directivity error correction is applied
R: refrection tracking Indicates that error correction is applied
S: source match Indicates that error correction is applied
T: transmission tracking Indicates that error correction is applied
X: indicates that isolation (crosstalk) error correction is applied
5. Reference position
Indicates the reference position of the corresponding trace. You can change the position with
REFERENCE POSITION .
6. Marker status
The active marker that is selected and one marker that was previously active are displayed.
7. Trace status
The status of each trace format and the value corresponding to the active marker are displayed.
For example, if the display is
CH0 LOGMAG 10dB/ 0.02dB , read as follows.
- Channel CH0 (reflection)
- Scale is 10dB
- Current value is 0.02dB
For active traces, the channel display is reversed.
8. Battery status
When a battery is installed and
D2 on the PCB is already mounted, an icon is displayed according to the battery voltage.
