-Turn on the fixed +5 volt power supply and connect the 9 volt battery to your circuit. Connect AWG1 output to F<​sub>​REF</​sub>​ as shown in figure 4. Configure AWG1 as a square wave with an amplitude of 5 V and an offset of 2.5 V ( 0 to 5 V swing ) and initially set the frequency to what you measured in step 1 when V<​sub>​IN</​sub> ​ was set to 2.5 V ( should be around 250 KHz ). Connect scope channel input CH1+ to the F<​sub>​REF</​sub>​ input and scope channel CH2+ to V<​sub>​SQR</​sub>​ output as shown in figure 6. You should ground the CH1- and CH2- inputs as well. Set the scope to trigger off the rising edge of channel 1 ( the F<​sub>​REF</​sub>​ signal ).+Turn on the fixed +5 volt power supply and connect the 9 volt battery to your circuit.
