Wandel-Goltermann PCM4 Channel Measuring
The PCM-4 PCM Channel Measuring Set can handle practically all PCM multiplexer measurements, and also measurements on the constituent subassemblies of digital exchanges. Transmultiplexer measurements are also possible because investigations between digital interfaces can be made. Single modules (e.g. CODECs) may also be checked as it is possible to carry out all measurements via 64 kbit/s interfaces.
* Compact instrument for A-A, A-D, D-A and D-D measurements to CCITT Rec. O.133, G.700-Series and North American standards (BN984/02).
