Measurement Using the Marker Control Fields:
• Position positions the marker on the screen. Displayed marker Freq and
Lvl are automatically updated.
• Marker To sets the marker to the signal with the largest Peak, the
signal with the Next largest Peak, to the Center Frequency, or to the
Reference Level.
Relative frequency and amplitude measurements such as filter bandwidth,
duplexer rejection/insertion loss, or harmonic level can be performed
using the “Delta” marker function.
The Delta marker function is performed by:
1. Setting the marker to the first point desired.
2. Position the cursor to the marker frequency and/or amplitude indicators.
3. Press the REF SET key.
Note that the readout now displays 0 and “Ref” below it.
4. Position the cursor to the Position field.
5. Move the marker along the displayed response.
The marker readout now displays the delta from the set reference
point.
To turn the reference set off:
• Press the REF SET key.
• Press the ON/OFF key.
