2.5.3 Right Panels – Signal Source

Figure 8a: WaveVision 5 main window command buttons

Open the Signal Source panel on the right side of the window and confirm that the

ADC12D1X00RFRB is available and confirm that it is selected. There are seven possible modes

of operation selectable here:

•

NonDES I ch –

Dual channel mode capturing and viewing the I-channel data

•

NonDES Q ch –

Dual channel mode capturing and viewing the Q-channel data

•

NonDES I and Q –

Dual channel mode capturing and viewing both the I- and Q-channel data

•

DESI Mode –

Double Edge Sample (interleaved) mode with I input

•

DESQ Mode –

Double Edge Sample (interleaved) mode with Q input

• DESIQ Mode –

Double Edge Sample (interleaved) mode with I and Q as input – shorts both I

and Q inputs together and must be externally driven by the same signal

• DESCLKIQ Mode –

Sampling Clock samples the I- and Q-channels 180º out of phase with

respect to one another – I and Q are not shorted together and must be externally driven by the

same signal

Double Edge Sampling (DES)

– Double edge sampling works much in the same way as single edge

sampling except that the signals is sampled both on the rising and falling edge of the sample clock. This

effectively doubles the sample rate. In this mode, both converters inside the ADC12D1X00RF work on a

common input signal. The various DES modes are selected from the Signal Source tab on the right side

and have requirements for how the inputs must be driven. See the datasheet for more details.
