應(yīng)用

• 探測高頻電源軌上的噪聲源

為什么使用電源軌探頭？

現(xiàn)代電子產(chǎn)品新增的功能、更高的密度、更快的開關(guān)速度，正推動著對更低的供電電壓的需求。設(shè)計(jì)人員需要放大電源軌，查找高頻干擾信號，測量紋波，在更緊張的容限下分析耦合效應(yīng)。示波器通常沒有足夠的偏置，把 DC 軌上的噪聲和紋波位移到屏幕中心，來進(jìn)行所需的測量。

TPR1000 和 TPR4000 探頭提供了低噪聲測量解決方案（示波器和探頭），這一點(diǎn)非常關(guān)鍵，以區(qū)分示波器和探頭的噪聲與被測的 DC 電源的噪聲和紋波。探頭中較高的輸入阻抗，可以限度地減少示波器負(fù)載對 DC 軌道的影響 (50 kΩ @ DC)。探頭提供的帶寬越高，能夠查看 DC 軌道上可能影響的數(shù)據(jù)信號、時鐘等信號的內(nèi)容（諧波、更快的紋波等）就越多。

TPR1000 和 TPR4000 為高速 (μP)、低功率（手機(jī)）和開關(guān)式電源市場中的功率完整性和驗(yàn)證工程師提供了同類秀的完整性解決方案。探頭設(shè)計(jì)提供了的噪聲、高帶寬及 60 V 偏置，擁有靈活的連接選項(xiàng)，可以解決客戶挑戰(zhàn)，同時有多個軟件包，能夠滿足數(shù)字功率管理市場的需求。

Detect noise sources on high frequency power rails

Why use a power rail probe?

New features, higher densities and faster switching speeds in modern electronics are driving demａnd for lower power supplies. The designer needs to amplify the power track, find high frequency interference signals, measure ripples, and analyze the coupling effect under more intense tolerances. An oscilloscope usually does not have enough bias to shift the noise and ripple on the DC track to the center of the screen to make the required measurements.

The TPR1000 and TPR4000 probes provide a low noise measurement solution (oscilloscope and probe), which is critical to distinguish the noise of the oscilloscope and probe from the noise and ripple of the DC power supply under test. Probe of high input impedance, can minimize the oscilloscope load impact on DC rail (50 k Ω @ DC). The higher the bandwidth provided by the probe, the more content (harmonics, faster ripples, etc.

The TPR1000 and TPR4000 provide the best integrity solutions of their kind to power integrity and verification engineers in the high speed (P), low power () and switching power markets. The probe design offers minimum noise, high bandwidth and 60 V offset, flexible connectivity options to address customer challenges, and multiple software packages to meet the needs of the digital power management market.
