| =====Quick Start Guide===== | =====Quick Start Guide===== |
| ====Selecting the DAC Output==== | ====Jumpers for Selecting the DAC Output==== |
| By default, jumpers JP4, JP5, JP6, and JP17 configure the AQM output to be observed at SMA output J6. 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 below. | Jumpers JP4, JP5, JP6, and JP17 select the output configuration. By default, the DAC output connected to the LPF and the ADL537x analog quadrature modulator. For selecting DAC output configuration, refer to Table 1 and Figure 2. |

| ====Jumper Options==== | ====Jumper for Selecting Power Supply==== |
| There are 7 pin jumpers on the evaluation board. The pin jumpers are corresponding to the 6 supplies on the board. They serve as ‘switches’ that determine if the LDOs on board or external supplies are used for each individual supply. They are shunted by default, which means on board LDOs are used. When an external supply is necessary, pull off the shunt from the corresponding supply and connect the external supply to the SMA jack close to the jumper. The seventh pin jumper configures the voltage of the IOVDD supply. Refer to the table below. | The evaluation board has a provision for on board or external power supply configuration. |
