因此谨慎的做法是定期地用静电计欧姆计来测量测试夹具和电缆的绝缘电阻，以保证其完整性。
Therefore, it's prudent to measure the insulation resistance of the test fixtures and cables periodically with an electrometer ohmmeter to ensure their integrity.
以下各段将讨论在进行低电平测量时对电缆和测试夹具的要求以及常用的连接器类型。
The following paragraphs discuss cable and test fixture requirements and types of connectors generally used when making low level measurements.
使测试夹具稳定。牢靠地固定或绑扎电子元件、导线和电缆。屏蔽应当牢靠、完善。
Stabilization of the test hookup. Securely mount or tie down electronic components, wires, and cables. Shielding should be sturdy.
仪器、开关卡、电缆和夹具中均可存在漏泄通路。
Such leakage paths may be present in the test instrument, switching cards, cables, and fixtures.
若开关、互连电缆和测试夹具没有合适的屏蔽，所产生的杂散信号（偏移）将威胁到被测信号。
Without proper shielding of the switches, interconnecting cables, and test fixturing, spurious signals (offsets) may be generated that will compromise the signal being measured.
在电缆连接器插头或测试夹具上可能会出现危险致死电压。
Lethal voltage may be present on cable connector jacks or test fixtures.
请使用合适阻抗的同轴电缆，并完全屏蔽测试夹具，以防大信号的漏泄。
Use the appropriate impedance coax cables, and completely shield the test fixture to prevent leakage of high level signals.
在测试夹具上为每个信号安装一个插座，用电缆将其连接到开关卡。
A receptacle for each signal is mounted at the test fixture, and the cables are used to connect them to the switch CARDS.
研究了在测量时同轴电缆线和测量夹具对微波滤波器性能的影响。
The influence of coaxial cables and test fixture on the performance of filters was investigated.
