Purple Scope Monitor
Red DUT source RF Out
Blue Reference Source RF out
1) CH 1 PLL Tune Line Connect the Ch 1 PLL Tune Voltage Out port (green) of the M9550A phase
detector module inside the PNTS chassis to the EFC port at the back of the REF
(PSG as reference) source using the BNC-to-BNC cable.
2) DUT to Sig/RF on PNTS Connect the RF output of the DUT source to the high-band RF input (1.2 to
40 GHz) labeled "Sig/RF" on the M9550 phase detector module using an SMA
cable
3) REF to Ref/LO on PNTS Connect the RF output port of the REF source to the high-band RF input (1.2 to
40 GHz) labeled "Ref/LO" on the M9550 phase detector module (blue) using an
SMA cable
4) MONITOR output to Scope Connect SMB-to-BNC cable from the "Monitor" output on the M9550 phase
detector (purple) to channel 1 of the oscilloscope
