The channel scanner mode can be applied to measure the signal power of multiple channels. The signal power is displayed in the bar graph or list form. At most, the signal power of 20 channels can be displayed. This can be divided into three modes according to the channel setting: channel scanner, frequency scanner and list scanner.

Channel scanner: Set the measured channel by setting the signal standard, starting channel and channel step.

Frequency scanner: Set the measured channel by setting the starting frequency and frequency step.

List Scanner: Set the measured channel by setting the list. The bandwidth and number of measured channels can be set in the above three modes.

1. Channel Scanner

Below is an example of the Channel Scanner mode, mainly involving the following procedures.

1) Press [Sweep]→[Channel Scanner]→[Signal Std], and set the signal standard of measurement.

2) Press [Sweep]→[Channel Scanner]→[Start Channel] and set the starting channel of measurement. In this case, the starting channel should meet the requirements of the selected signal standard.

3) Press [Sweep]→[Channel Scanner]→[Number of Channels], and set the number of measured channels. At most 20 channels can be measured at the same time.

4) Press [Sweep]→[Channel Scanner]→[Channel Step] and set the channel step of measurement. A certain number of channels will be measured with the starting channel as the initial channel, based on the set channel step.

5) Press [Sweep]→[Display Graph Table] and enable the graph display mode.

6) Press [Sweep]→[Power Display Curr Max] and enable the maximum option. Set the maximum power of each displayed channel.

2. Frequency Scanner

Below is an example of the Frequency Scanner mode, mainly involving the following procedures.

1) Press [Sweep]→[FScan]→[Start Freq], and set the center frequency of the starting channel.

2) Press [Sweep]→[FScan]→[Step Freq], and set the frequency step of the measured channel.

3) Press [Sweep]→[FScan]→[Bandwidth], and set the bandwidth of the measured channel.

4) Press [Sweep]→[FScan]→[Number of Channels], and set the number of measured channels. At most 20 channels can be measured at the same time.

5) Press [Sweep]→[Display Graph Table] and enable the graph display mode.

6) Press [Measure]→[Power Display Curr Max], and enable the “Current” option. Set the current power of each channel.

3. List scanner

Below is an example of the Frequency Scanner mode, mainly involving the following procedures.

1) Press [Sweep]→[MScan]→[Edit List] and edit the channel list to be swept. The information of each channel can be set by setting the signal standard and channel number or setting the frequency and bandwidth in the list.

2) Press [Sweep]→[MScan]→[Number of Channels], and set the number of measured channels. At most 20 channels can be measured at the same time.

3) Press [Sweep]→[Display Graph Table] and enable the graph display mode.

4) Press [Sweep]→[Power Display Curr Max], and enable the “Current” option. Set the current power of each channel.
