Selecting the DAC Outputs
By default, solder jumpers JP4, JP5, JP6, and JP17 configure the AQM output to be observed at SMA output J6. This jumper setting
is shown in Figure 4 b). This connects the DAC outputs to the LPF and the ADL537x analog quadrature modulator. The modulator
LO input can be sourced through SMA connector J15 (LO_IN). The clock level into the modulator should be set to about 3 dBm. In order
to observe the DAC outputs at Jumpers J3 and J8, the solder jumpers need to be repositioned as shown in Figure 4 a).
