Performance:

* more accurate QAM performance index detection and analysis -- average power, MER, BER (before/after), constellation.

* faster spectrum analysis function and power measurement, real and fast reflection of the actual situation of the channel.

* longer working hours, built-in high-capacity lithium battery, more than 5 hours of continuous boot work, can take the charger for a long time.

* provide the qualified judgment function of digital TV indicators, and the test is simple and convenient.

* provide network interface.

* support multiple DVB modes: 16QAM, 32QAM, 64QAM, 128QAM, 256QAM.

* QPSK COFDM power detection.

* positive and reverse system detection.

* digital TV indicator and comprehensive analog TV indicator (level, V/A, slope, limit) automatic detection function.

* high definition and ultra-wide temperature of FSTN liquid crystal band 4 gray scale display, have good visual effect.
