Single-ended BNC input
The displayed voltage is the center contact relative to the BNC shell.
The DSO150 Shell is a single-channel oscilloscope kit with a BNC input, an external DC jack and a selectable square-wave compensation output.
Connect the probe tip to the measured signal.
| Pin | Signal | Direction | Function |
|---|---|---|---|
| J1 center | AIN Analog input | Analog input | Connect the probe tip to the measured signal. |
| J1 shell | AGND Analog return | Analog return | Connect the probe ground clip to the circuit’s common return. |
| J7 center | DC_IN Supply input | Supply input | Positive contact of the 5.5 × 2.1 mm barrel jack. |
| J7 sleeve | DC_RETURN Supply return | Supply return | Outer sleeve of the barrel jack. |
| J6-1 | DC_IN Supply input | Supply input | Positive contact of the alternate PCB power header. |
| J6-2 | DC_RETURN Supply return | Supply return | Ground contact of the alternate PCB power header. |
| J8 | TESTSIG Square-wave output | Square-wave output | Selectable 0.1 V or 3.3 V square-wave output. |
The displayed voltage is the center contact relative to the BNC shell.
The barrel jack and the alternate two-pin header feed the same supply input.
Use the scope’s own probe and test contact for compensation.
