Custom interface cables will need to be made. You can remove the full size XLR from the cables provided, and wire in an RCA plug. Connect the signal to the wire that went to pin 2 and connect the other wires (1 and 3 on the XLR) to the ground.

If you wish to build the cable yourself, the connector that Tektronix supplies as an accessory to the VM700T option 40 is P/N 131-5272-00. The manufacturer is Switchcraft, and their part is TA3ML.
