Anritsu PDC Signalling Tester Model MD1623B
Specifically designed for testing of both tx and rx relating to the now obsolete Japanese cellphone system, PDC. Similar (in some ways) to GSM in that it used TDMA, operating in the 800Mhz & 1.8Ghz frequency bands (2G)
**MODULE ONLY**
PDC is old cellular technology although still in use until 2012, at which time the last Japanese provider turned off their equipment.
