(Option 30)
Introduction
Option 30 provides measurement capabilities for testing ISDB‑T networks, which are terrestrial digital broadcast networks. Note that Option 9 (IQ Demodulation Hardware) may be required in your instrument in order to use Option 30. The ISDB‑T Signal Analyzer includes seven types of measurements: Field Strength, Modulation Analysis, Spectrum Mask, Phase Noise, Spurious Emissions, BER measurements, and Spectrum Monitor.
Field Strength
Measures channel power and field strength.
Modulation Analysis
Measures modulation error ratio (MER), modulation wave frequency, sub‑carrier MER, delay profile, and frequency response.
Spectrum Mask
Evaluates the input signal spectrum.
Phase Noise
Measures CW frequency and the local phase noise of the transmitter.
Spurious Emissions
Measures spurious elements and the interfering waves that affect the broadcast quality.
BER (Option 79):
Measures Bit Error Rate, Packet Error Rate, Transmission Multiplexing Configuration Control (TMCC), MPEG TS Bit Rate, and Channel Power.
Spectrum Monitor
Displays the spectrum of the input signal.
After a test has been selected from the Meas Selection (1/2) Menu (Custom and Easy), choose one of three methods for setting up a measurement: Batch, Easy, or Custom. When either Custom Measurement mode or Easy Measurement mode has been selected, all measurements in the Meas Selection (1/2) menu are set up for that measurement mode. In Batch Measurement mode, a limited group of measurements are available (refer to Batch Measurement Setup).
Screen images of measurements, as shown in this document, are examples. The images on your instrument may differ in appearance.
The main menu keys in this instrument mode are:
Frequency/Level Meas Selection Meas Setup Execute Measure Save Files
For BER measurements, the Execute Measure main menu key becomes a Start Measurement / Stop Measurement key.
