Release time :2021.03.14 Reading quantity:58 source:Salukirf, original

Saluki S3302 portable spectrum analyzer is a high frequency handheld instrument. S3302 portable spectrum analyzer has a compact design, very suitable for field measurement. 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.

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

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

•   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.
