QM1003-0.5-18-2 Dual Channel RF Downconverter

User Manual

2. General Description

The QM1003-0.5-18-2 is a Dual Channel RF Downconverter housed in a 1U box. The QM1003-0.5-18-2
is controlled either through the onboard USB or TCP/IP connection. The QM1003-0.5-18-2 delivery kit
contains a user manual, power supply, and USB A-

µ

B cable. A model of the QM1003-0.5-18-2 is shown

below in Fig. 1.1.

Figure 1.1:

QM1003-0.5-18-2 Dual Channel RF Downconverter system

The QM1003-0.5-18-2 Dual Channel RF Downconverter has been equipped with Option -100, which adds
Local Oscillator (LO) sources, making the QM1003-0.5-18-2 a self contained system, requiring only the
externally applied RF or IF signals for proper operation. Option -205 shifts the IF frequency range from
750-1250MHz to 2-3GHz. The Local Oscillators (LOs) in the QM1003-0.5-18-2 are locked to a common
internal reference. The user has the option of supplying their own reference through the BNC connector
located on the back panel of the QM1003-0.5-18-2.
