R&S®EFA90/93 Test Receiver (M/N Analog TV)
New high-end M/N TV demodulator
Rohde & Schwarz provides a high-end measurement device that can cover all application areas from R&D to field measurements. This R&S EFA model was created to offer the best performance and the most useful features to test standard M/N transmitters under optimal conditions. To accomplish this, a sound trap filter has been integrated in the unit as well as synchronous and envelope detectors, a BTSC audio decoder and additional features!
To further protect your investment, the unit can be updated by means of options to demodulate and analyze the upcoming digital TV standards ATSC/8VSB and ITU-T J.83/B. These unique features make the new R&S EFA family members THE measurement devices for the present and the future!
R&S EFA 90/93 characteristics
Fully compatible with the FCC standard, the R&S EFA 90/93 models receive and demodulate any analog TV signals to standard M/N (NTSC/BTSC and PAL). All key parameters for demodulating the received signal can be automatically or manually selected:
- Switchable video bandwidth (sound trap)
- Switchable group delay correction
- Switchable synchronous detector (5 different modes)
- Demodulation using intercarrier method
- Balanced audio outputs
- Measurement functions for
- vision/sound carrier spacing (level and frequency)
- FM sound carrier and pilot deviation
- Measurement of video modulation depth and residual picture carrier
- Input of any IF frequency with the aid of the R&S EFA-B3 option: frequency range continuously tunable from 5 MHz to 1000 MHz
- Special function: invert spectrum feature (with option R&S EFA-B3)
