| 7 | 1 | Jack Linke | XTest1 makes has two main RF paths: |
| 8 | 1 | Jack Linke | * The main switching and active attenuation path. This path has two inputs (one for lower power, and one for higher power, immediately attenuated by 20dB), and a single output. |
| 9 | 1 | Jack Linke | * An insertion loss path used to measure the insertion loss of the switch and active attenuator |
| 10 | 1 | Jack Linke | |
| 11 | 1 | Jack Linke | The RF Switch and the active attenuator are controlled by an AVR ATMega48PA/88PA/168PA microcontroller. |
