This chapter describes DVB‑T/H single frequency network (SFN) setup and measurement for signal power and signal analysis with Option 78, which requires that your instrument also has Option 64 installed. Note that Option 9 (IQ Demodulation Hardware) may also be required in your instrument in order to use Option 78. You can measure channel power along with the field strength and power of each incoming signal even with several incoming multipath signals. The time for impulse response measurements is longer in order to allow for the measurement of signals coming from distant sites in the network.
