Table 3The MultiLab accepts seven commands. Most commands require two parameters, except the DC voltmeter, which expects no parameters but returns a voltage instead. Although it is not shown here, the fourth command also requires the actual waveform array to be sent after the two parameters shown.
| Command number | Description | Parameter #1 | Parameter #2 |
| 1 | Pulse generator | Period | Pulse width |
| 2 | Wave generator | Frequency | Wave type |
| 3 | Stepper drive | Step rate | Sequence type |
| 4 | Store arb wave | Waveform number | Waveform depth |
| 5 | Select arb wave | Waveform # | 0 (not used) |
| 6 | DC voltmeter | 0 (not used) | 0 (not used) |
| 7 | DC reference | Voltage | Range (V or mV) |
