## README

智能仪器仪表接口。

## 安装

```bash
pip install instrument
```

安装后还需要本机可用的 VISA 后端，以便 `pyvisa` 能连接实际仪器。

## 基本用法

```python
import pyvisa

from instrument import is_supported, make_


rm = pyvisa.ResourceManager()

signal_generator = make_(
    "AGILENT::33512B",
    rm.open_resource("USB0::0x0957::0x2807::MY62000107::INSTR"),
)
signal_generator.configure(
    channel=1,
    wave="WAVE::SINE",
    amplitude=2.5,
    offset=1.25,
    key="frequency",
    beep=True,
)
signal_generator.set(key="frequency", value=1000)
signal_generator.stop()

dmm = make_(
    "KEITHLEY::DMM6500",
    rm.open_resource("USB0::0x05E6::0x6500::04645572::INSTR"),
)
if is_supported("KEITHLEY::DMM6500", "MEASURE", "VOLTAGE_DC"):
    dmm.configure(key="voltage_dc", param={"range": 10, "nplc": 1})
    value = dmm.get()
    print(value)
```

## 当前导出 API

- `make_(name, resource)`: 根据仪器型号创建设备对象
- `is_supported(name, category, key)`: 查询型号是否支持某项能力
- `VisaBasedInstrument`: VISA 仪器基类
