S3302 Handheld Spectrum Analyzer Field Strength Function

The field strength measurement is indispensable in radiation strength measurement of the tested equipment and can be divided into three modes: PScan, FScan and MScan.

l  PScan: Observe the offset, amplitude and field strength of the current point by setting the point frequency.

l  FScan: Observe the amplitude and field strength changes within a certain frequency range by setting the starting frequency, step frequency and number of points.

l  MScan: Observe the amplitude and field strength of frequency points in the list by recalling the edited or saved list.

1. [PScan]

Main operation procedures of [PScan]:


1) Press [Measure]- [PScan] to enable the point frequency measurement mode.


2) Press [Frequency]- [Frequency] and set the point frequency within the range of  [1MHz, 44.1GHz].


3) Press [BW]- [BW] and set the bandwidth as 150Hz, 300Hz, 600Hz, 1.5kHz, 2.4kHz, 6kHz, 9kHz, 15kHz, 30kHz, 50kHz, 120kHz or 150kHz.


4) Press [Sweep/Antenna]- [Recall Antenna], and select the antenna factor file.


5) Press [Demod] and set the demodulation type and volume.


The schematic diagram of PScan mode is shown in the figure below (example).

2. FScan

Main operation steps of FScan:


1) Press [Measure]- [FScan] to enable the frequency sweeping mode.


2) Press [Frequency]- [Start Freq] and set the starting frequency of sweeping.


3) Press [Frequency]- [Step Freq] and set the step frequency of sweeping.


4) Press [Frequency]- [Points] and set the number of sweeping points.


5) Press [BW]- [BW] and set the bandwidth as 150Hz, 300Hz, 600Hz, 1.5kHz, 2.4kHz, 6kHz, 9kHz, 15kHz, 30kHz, 50kHz, 120kHz or 150kHz.


6) Press [Sweep/Antenna]- [Recall Antenna], and select the antenna factor file.


7) Press [Sweep/Antenna]- [Dwell Time  Man], and set the dwell time.


8) Press [Sweep/Antenna]- [Dwell Time Off On] to enable or disable the dwell time.


9) Press [Marker]- [Marker Off On] to enable or disable the marker.


10) Press [Peak] to directly set the marker at the maximum point


The schematic diagram of FScan mode is shown in the figure below (example).

3. MScan

Main operation steps of MScan:


1) Press [Edit List]- [Edit List] and edit the current list.


2) Press [Measure]-[MScan] to enable the MScan mode.


3) Press [Frequency]- [Step Freq] and set the step frequency of sweeping.


4) Press [Frequency]- [Points] and set the number of sweeping points.


5) Press [BW]- [BW] and set the bandwidth as 150Hz, 300Hz, 600Hz, 1.5kHz, 2.4kHz, 6kHz, 9kHz, 15kHz, 30kHz, 50kHz, 120kHz or 150kHz.


6) Press [BW]- [BW] and set the bandwidth as 150Hz, 300Hz, 600Hz, 1.5kHz, 2.4kHz, 6kHz, 9kHz, 15kHz, 30kHz, 50kHz, 120kHz or 150kHz.


7) Press [Sweep/Antenna]- [Recall Antenna], and select the antenna factor file.


8) Press [Sweep/Antenna]- [Dwell Time Man], and set the dwell time.


9) Press [Sweep/Antenna]- [Dwell Time Off On] to enable or disable the dwell time.


10) Press [Marker]- [Marker Off On] to enable or disable the marker.


11) Press [Peak] to directly set the marker at the maximum point.
