DS1001 Digital Signal Level Meter 
 The DS1001 is a suitable instrument for CATV system maintenance testing of its small size (16 × 13 × 6.5), light weight (less than 600 g), using a long time (more than 5 hours). The ultra-rugged appearance and internal structure design, anti-5 m hard surface free fall; dual-channel measurements show that, convenient and practical. The C / N, V ??/ A, slope, trunk voltage measurement.
