3. Screen Reference
The following display fields show the measurement results:
a. The variable increment softkey is activated. Refer to "Variable Incre-
ment Softkey" on page 60.
Display Field Description
Peak
The absolute peak power and frequency are shown.
Marker
a
a. The frequency resolution is 1 kHz or 2 kHz due to the measurement
resolution of 1.59 kHz.
The frequency and amplitude readouts at the marker position
are shown when activated by the Knob MKR
/Cursor softkey
as follows:
o -------- MHz ---- dBm: The absolute frequency and
amplitude of the marker readouts are shown.
o ( ---- kHz ---- dB ): The relative frequency and
amplitude of the marker readouts are shown.
0-400 kHz span:
M1: +200 kHz,
M2: +250 kHz
The amplitude data at +200 kHz and +250 kHz offsets are also
shown in the left lower screen corner.
±100 kHz span:
M1: −67.7 kHz,
M2: ±0 kHz,
M3: +67.7 kHz
Three peak amplitudes at around the offsets M1, M2, and M3
from the center frequency are measured and shown with those
corresponding frequencies
b
in the left lower screen corner.
b. The frequency resolution is 1 kHz due to the measurement resolution
of 0.79 kHz. This will cause to have two amplitude readouts at the
same frequency.
