Supply Deli Strength Meter DS2100B Digital TV Signal Strength Meter Digital BERT Zhengzhou Megumi instrumentation 0371-66227105 www.5117hm.com 

 Product Description: 
 The DS2100B high-speed microprocessors to achieve fast power spectrum scanning measurement, but also for digital, analog mixed network measurement and two-way network measurement. 

 The main features 
 ● more accurate QAM performance testing - the average power, MER, BER (RS front / rear) 
 ● longer working hours, built-in high capacity lithium battery, more than five hours of continuous power, can bring the charger to work long hours 
 ● support a variety of DVB mode: 64QAM, 256QAM 
 ● QPSK, COFDM power to detect 
 ● forward and reverse system detection 
 ● automatic analog and digital channels to create function, applicable to any network detection 
 ● indicators of digital TV and full analog TV indicators (level V / A, slope, limit) automatic detection 
 ● High Definition, Wide Temperature FSTN LCD, four gray-scale display, with good visual effects
