特點(diǎn) | 優(yōu)勢(shì) |
| 可編程恒定電壓源 (50–500V) | 支持高速、高電阻測(cè)量。 |
| 可編程恒定輸入源 (0–50mA)，帶有弱電流電路鉗 | 有助于防止低電阻測(cè)量期間出現(xiàn)器件應(yīng)力或器件損壞。 |
| 模塊化架構(gòu) | 輕松適用于單充氣機(jī)或雙充氣機(jī)測(cè)試、單工位或工位測(cè)試臺(tái)以及混合設(shè)備/信號(hào)應(yīng)用。 |
| GPIB、RS -232 和數(shù)字 I/O 接口 | 輕松與外部測(cè)試硬件集成。 |
| 兩年模塊校準(zhǔn)周期 | 減少維護(hù)成本和系統(tǒng)停機(jī)時(shí)間。 |
The Model 2790 uses the forced constant-current method to measure resis-tances less than 1kW . In this technique, the instrument sources a constant current (I) to the resistance and measures the resulting voltage (V) . The amount of current sourced is programmable from 0–50mA . Resistance (R)is calculated (and displayed) using the known current and measured volt-age (R = V/I) . A 20mV dry circuit clamp is available at sourcing levels up to 1mA for preserving the oxide layers on connectors and other components .
