Please refer to your instrument User Guide for directions about selecting the DVB‑T/H SFN mode.
Antenna Setup
The antenna attaches to the instrument with a coaxial cable. The antenna and coaxial cable are not supplied with the instrument and must be procured separately.
The antenna factors are different for each antenna. Refer to the documentation for your antenna. Also, remember to add the cable loss to the measurement correction table. You can use Master Software Tools (MST) to update your antenna and coaxial cable lists. For directions about updating these lists, refer to the Master Software Tools documentation (available from www.anritsu.com).
1. Attach the antenna to the Spectrum Analyzer connector on top of your instrument (refer to the User Guide for your instrument).
c. Press the Antenna (Correction Level) submenu key.
d. In the Select Antenna list box, scroll to the desired Anritsu antenna model number by using the Up/Down arrow keys or the rotary knob, and press the rotary knob or the Enter key to select it. Note that the Left/Right arrow keys jump directly to the top and bottom of the antenna list.
Setting up the Measurement Frequency
The measurement frequency can be set by entering the center frequency or by selecting the applicable signal standard and channel, which allows the instrument to automatically set the frequency.
To set the measurement frequency by entering the center frequency:
1. Press the Frequency main menu key.
2. Press the Center Freq submenu key.
3. Enter the required frequency by using the keypad, the arrow keys, or the rotary knob. When entering a frequency by using the keypad, the submenu key labels change to GHz, MHz, kHz, and Hz. Press the appropriate unit key. Pressing the Enter key has the same effect as pressing the MHz submenu key. The current setting is shown at the top of the instrument settings summary column on the left side of the screen.
To set the measurement frequency by selecting a signal standard:
1. Press the Frequency main menu key.
2. Press the Signal Standard submenu key to open the Signal Standards dialog box. Select the desired signal standard. When a signal standard is selected, the center frequency for the channel of the selected standard is automatically tuned.
3. Press the Channel submenu key to open the Channel Editor dialog box and set the channel within the specified range.
4. If necessary, press the Frequency Offset submenu key to offset the channel frequency (using the values from the Select Frequency Offset dialog box).
Bandwidth Setup
1. Press the Bandwidth submenu key to display a set of available bandwidths: 5 MHz, 6 MHz, 7 MHz, or 8 MHz.
2. Use the Up/Down arrow keys or the rotary knob to highlight the applicable bandwidth in the list, and then press the Enter key to set the bandwidth. The selected bandwidth is displayed in the instrument settings summary column.
Amplitude Setup
1. Press the Amplitude main menu key to open the Amplitude Menu.
2. Press the Auto Reference Level submenu key to allow the instrument to set an optimum reference level, or press the Reference Level submenu key to manually set the reference level.
When the Reference Level Editor dialog box opens, enter the desired reference value.
3. If the input signal is weak, then press the Pre Amp sub menu key to toggle this function On.
4. Press the Impedance sub menu key to toggle through to the desired impedance parameter: 50 ohm, 75 ohm, or Other. If you select Other, then the Impedance Loss submenu key is displayed in the menu. Impedance Loss is set manually.
Press the Impedance Loss sub menu key to open the Impedance Loss Editor dialog box and select a dB loss level within the displayed range.
2. Press the Meas Mode submenu key to open the Select Meas Mode list box and choose between Single or Continuous measurement sweeps.
3. Press the Trigger Sweep submenu key to begin a sweep (a single measurement sweep if Meas Mode is set to Single, or multiple measurement sweeps if Meas Mode is set to Continuous).
If Meas Mode is set to Continuous, then pressing Trigger Sweep interrupts any measurement sweep that is in process and restarts a new measurement sweep.
4. Press the Detect Parameter Once submenu key to detect for Mode, GI, Modulation, and Hierarchy parameters.
5. Press the Advanced Settings submenu key to continue measurement setup by using the Meas Setup (2/2) Menu.
6. Press the Mode, GI submenu key to select the desired width of the guard interval.
7. Press the Modulation submenu key and choose the desired modulation type: QPSK, 16QAM, and 64QAM.
8. Press the Hierarchy, Alpha submenu key and choose: None, 1, 2, or 4.
9. Press the Spectrum Reverse submenu key to toggle between On and Off. The current setting is underlined. Use Spectrum Reverse to measure a signal whose sub carrier location is inverted on the frequency axis, such as the IF signal of the transmitter.
10. Press the Back submenu key to return to the Setup (1/2) menu.
