Batch measurement mode allows you the option of running multiple tests for multiple channels. Batch mode setup consists of a combination of minimal setup procedures and default measurement parameters. You are allowed to select channels from either the UHF or UHF (Brazil) channel maps. If you select IF or None, then the channel map is automatically set to UHF.
Batch measurement mode is not available for BER measurements.
Follow this procedure to set up for Batch Measurement mode when your instrument is currently in either Easy Measurement mode or Custom Measurement mode.
1. Press the Frequency/Level main menu key and then press the Channel Map submenu key to open the Select Channel Map list box.
2. Select UHF or UHF (Brazil) and then press Enter.
3. Press the Meas Selection main menu key, then press the More submenu key.
4. Press the Batch submenu key. A warning window opens. Press Enter to continue or Esc to abort.
5. The Batch Measurement configuration window is displayed, and the Batch Measurement Setup Menu is displayed. Note that no Frequency/Level main menu key and no Save Files main menu key are available.
Batch Measurement Setup Menu
Select Channel
Press this submenu key to open the Select Channel Editor list box.
Meas Item Setup OnOff
Press this submenu key to turn each of the 4 measurements On or Off.
Save Waveform On Off
Press this submenu key to turn On or Off the ability to save measurement waveforms with the measured results.
Impedance 50 Ohm 75 Ohm Other
Press this submenu key to toggle the selection to 50 ohm, 75 ohm, or Other impedance value. Selecting 75 ohm selects the 7.5 dB loss of the Anritsu 12N50‑75B adapter. For other adapters, select “Other” and enter the appropriate loss.
Impedance Loss
This submenu key is displayed only when the Impedance submenu key is set to Other. Press this submenu key to open the Impedance Loss Editor dialog box and set a dB value.
Set the impedance loss in the range of 0.0 dB to 100.0 dB (in 0.1 dB steps) when the impedance is set to Other (which is also 75 ohms). Set 1.9 dB when using the MA1621A impedance transformer as the impedance converter.
Antenna (Correction Level)
Press this submenu key to open the Select Antenna list box. Scroll through to the desired Anritsu antenna model number by using the Up/Down arrow keys or the rotary knob. Highlight the antenna model number, and then press Enter.
Batch Setup
1. Press the Select Channel submenu key to open the Select Channel Editor dialog box.
The Select Channel Editor dialog box displays the available channels (Channel column) and a list of channels that have been selected for measurement (Meas Object column). Refer to Figure: Select Channel Menu (Batch Measurement Mode).
a. Use the Up/Down arrow keys or the rotary knob to scroll through the list of channel numbers. Highlight a desired channel number and then press the Add Channel to Meas Object submenu key. Repeat this step until the desired channels are listed in the Meas Object column of the Select Channel Editor dialog box.
If undesired channel numbers are present in the Meas Object list, then highlight the desired channel numbers in the Channel list and press the Delete Channel from Meas Object submenu key. You can also press the Delete All Channels from Meas Object submenu key.
b. Press Enter when you are done selecting channels.
Note
Up to ten channels can be selected for batch measurements. The Add Channel to Meas Object submenu key does not respond after ten channels are included in the Meas Object list.

Add Channel to Meas Object
Press this submenu key to add the highlighted channel number (in the Channel column) to the Meas Object column list.
Delete Channel from Meas Object
Press this submenu key to delete the highlighted channel number (in the Channel column) from the list in the Meas Object column.
Delete All Channels from Meas Object
Press this submenu key to delete all of the channels from the Meas Object column.
2. Select the measurements that are to be performed on the selected channels.
a. Use the Up/Down or Left/Right arrow keys or the rotary knob to move the green cursor to the desired measurement (displayed at the top of the measurement screen): Field Strength, CH Power, Modulation Analysis, or Spectrum Mask. You can select any or all of these four measurements.
b. Press the Meas Item Setup OnOff submenu key to turn On or Off a highlighted measurement. A check mark in the box to the left of the measurement name indicates that the measurement is selected.
3. To save the measurement waveforms of the test, press the Save Waveform submenu key (if necessary) so that On is underlined. Measurement waveforms are saved to file with the extension _GRP.CSV.
4. Press the Impedance submenu key to toggle through the 3 settings. Select one of the three parameters: 50 ohm, 75 ohm, or Other. The current selection is underlined.
a. If Other is selected, then the additional Impedance Loss submenu key is displayed.
b. To configure the impedance loss, press the Impedance Loss submenu key and use the Up/Down arrow keys, the rotary knob, or the numeric keypad to set a value.
c. The Impedance Loss Editor dialog box and the Units menu are displayed. When using the numeric keypad, enter a value and then press the dB submenu key or press Enter to set the value.
The impedance loss setting range is 0 dB to 100 dB in 0.1 dB increments. The Up/Down arrow keys change the impedance loss value in 1 dB steps. The rotary knob changes the impedance loss value in 0.1 dB steps.
5. Press the Antenna (Correction Level) submenu key to open the Select Antenna list box. Scroll through to the desired Anritsu antenna model number by using the Up/Down arrow keys or the rotary knob. When the desired Anritsu antenna model number is highlighted, press Enter.
Note
Impedance, impedance loss, and antenna model number are displayed at the bottom of the Batch Measurement configuration display.
6. Press the Execute Measure main menu key to begin testing. While the batch measurement is being completed, the Execute Measure main menu key is replaced by a Stop Measure main menu key. Use the Stop Measure main menu key to abort the batch measurement.
As test measurements are being made, “Measuring” is displayed at the top of the measurement display. After the last selected measurement is complete, the Spectrum Monitor measurement runs automatically. The Batch test is complete after the Spectrum Monitor measurement is completed.
Batch Measurements
Field Strength, Channel Power, Modulation Analysis, and Spectrum Mask of up to 10 broadcast channels can be measured in series. Channel Power is measured during Field Strength measurements.
CW Frequency, Phase Noise, and Spurious Emissions are not measured.
When the Channel Map selection is UHF, a screen message displays “Batch Measurement”. When the Channel Map selection is UHF (Brazil), a screen message displays “Batch Measurement (Brazil)”.
Value calculated from the table of antenna correction factors for the first antenna that is listed in the Select Antenna list box and also from the frequency
1 Setting can be changed while in Batch Measurement mode.
