供應(yīng)二手HP437B功率計(jì)
The Agilent 437B power meter is a low-cost, high-performance, single-channel, programmable, average power meter compatible with the 8480 family of power sensors. Depending on which power sensor is used, the 437B can measure from -70 dBm (100pW) to +44 dBm (25W) at frequencies from 100 kHz to 110 GHz.
Designed for the ATE systems and demanding benchtop measurements, the 437B power meter makes fast, accurate, and reliable average power measurements. Only three inches high and half rack wide, the 437B minimizes the use of critical rack space in ATE systems. The advanced plastics technology used in the 437B cabinet combines the light weight of plastic with the shielding effectiveness of metal, making the 437B the only power meter to meet MIL-STD-461C EMI specifications.
- Power reference for automatic calibration and zeroing
- Duty cycle entry for a convenient peak power representation of the measurement average power
- Ten preloaded sensor card factors versus frequency
- Frequency Range: 100 kHz to 110 GHz
HP437B功率計(jì)價(jià)格低、性能好,是一臺(tái)單通道可編程的平均功率計(jì),它可與HP8480系列熱偶和二極管功率探頭配套使用。根據(jù)所使用的功率探頭,HP437B可在100kHz至50GHz頻率范圍內(nèi)測(cè)量從-70dBm(100pW)到+44dBm(25W)的功率。
為ATE系統(tǒng)和需要臺(tái)式測(cè)量而設(shè)計(jì)的HP437B功率計(jì)能完成快速、精確和可靠的平均功率測(cè)量。HP437B占用ATE系統(tǒng)中的標(biāo)準(zhǔn)機(jī)架空間少,只有3英寸高和半機(jī)架寬。HP437B機(jī)箱采用*的塑料工藝和具有金屬屏蔽效果的輕塑料,使HP437B成為滿足MIL-STD-461C EMI規(guī)范的*功率計(jì)。
現(xiàn)代的和具有靈活特點(diǎn)的設(shè)置使這種功率計(jì)能很方便地用在任何場(chǎng)合。
