Page 18: Purpose And Function
Figure 2-1 M1749A used as an RF/mmWave interface On the left side of the M1749A in the diagram, the Tx IF In port takes an input from the test system and upconverts it to the higher range of the DUT. Signals received from the DUT are downconverted and returned to the test system from the Rx IF Out port. - Page 19 USB controller and trigger lines shown in the illustration. The supplied AC/DC adapter provides a 19 VDC power input to the M1749A (this can also be done by a DC power supply, if one is included in the system steup).

Page 20: Initial Inspection
— Contact the nearest Keysight Technologies office. — Keep the shipping materials for the carrier’s inspection. — If you must return a test set to Keysight Technologies, use the undamaged original or comparable shipping materials. See “Returning the M1749A for Service”... -
Page 21: Location And Mounting
Quick Start Location and Mounting Location and Mounting It is recommended to suspend the transceiver above the Device Under Test (DUT), with the mmWave port pointed downwards at the DUT, so that heat given off by the transceiver will rise away from the DUT. Leave a minimum clearance of 2.5 inches (7 cm) around the transceiver. - Page 22 Quick Start Location and Mounting Getting Started Guide...

These ports are Trig 2 required if the M1749A is controlled by way of the USB port. They are not required if the M1749A is controlled by way of the Control port, which incorporates trigger signals (however, Trig 1 even if the Control port is used, these trigger ports remain available for use).
- Page 28 This 3.5 mm connector accepts a variable-frequency input from the LO Out connector on the LO In front panel. This input is mixed with another input to the M1749A (9.6 GHz In) to generate the (see Caution below) LO input to the Transmitter Upconverter and the Receiver Downconverter. Torque wrench required.

Page 32: Simplified Block Diagram
Simplified Block Diagram The simplified functional block diagram below shows how signals to and from the S9130A system front panel (the left side of the M1749A in the illustration below) interface with the Tx upconverter and Rx downconverter, and how the upconverted and downconverted signals interface with the DUT-facing ports of the test head (the right side of the illustration). -
Page 33: Signal Routing
— Red: variable-frequency LO input to the M1749A, used in generating an LO input to the upconverter and downconverter. — Brown: fixed 9.6 GHz input to the M1749A, used in generating an LO input to the upconverter and downconverter. — Orange: generated LO signal to the upconverter and downconverter. - Page 34 Functionality Signal Routing The Tx/Rx ports are half-duplex: each one can function as a transmit port or a receive port (although not simultaneously). In the illustration below, the green transmit path can be routed either to RF Tx/Rx 1 (as in the upper picture) or to RF Tx/Rx 2 (as in the lower picture).
