Time Analysis (Time Mode)
WCA230A & WCA280A User Manual
3- 105
C/N (Carrier to Noise ratio) is measured at the offset frequency from the carrier.
Jitter is also calculated from the phase noise data.
Meas Setup Menu.
The following items are provided in the Meas Setup menu for
Phase Noise measurement (see Figure 3--74).
Carrier Threshold Level.
Sets the threshold for carrier detection. A signal with
amplitude above the threshold is detected as a carrier.
Setting range: --100 to +30 dBm (default: --20 dBm)
Carrier Bandwidth.
Sets the carrier bandwidth.
Setting range: Span/100 to Span/2 (default: Span/100)
C/N Sideband.
Selects the sideband for measuring phase noise.
H
Upper.
Default.
Measures the upper sideband.
H
Lower.
Measures the lower sideband.
Minimum Offset Frequency...
Sets the minimum frequency in the phase noise
measurement range as the offset from carrier frequency.
Setting value:
10 Hz (default), 100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz, or 10 MHz.
Maximum Offset Frequency...
Sets the minimum frequency in the phase noise
measurement range as the offset from carrier frequency.
Setting value:
100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz, 10 MHz, or 100 MHz (default)
Rj Start Offset Frequency.
Sets the random jitter measurement start frequency
as the offset from carrier frequency.
Setting range: 10 Hz to Rj Stop Offset Frequency set value (default: 10 Hz)
Rj Stop Offset Frequency.
Sets the random jitter measurement stop frequency
as the offset from carrier frequency.
Setting range: Rj Start Offset Frequency set value to 100 MHz
(default: 100 MHz)
NOTE
. The integrated phase noise and random jitter will be calculated if the
frequency range from Rj Start Offset Frequency to Rj Stop Offset Frequency is
within the range from Minimum Offset Frequency to Maximum Offset Frequency.
