RP4030 Active Voltage Rail Probe
The Teledyne LeCroy RP4030 Power Rail Probe meets the specific requirements of those who need to acquire a low-voltage DC signal as part of a:
-
Comprehensive power integrity, digital power management IC (PMIC), voltage regulator module (VMR), point-of-load (POL) switching regulator, or low-dropout regulator testing
-
Complete embedded power management system that includes PMICs, VRMs, POLs, and LDOs
The RP4030 will faithfully acquire a low-impedance, low-voltage DC power/voltage rail signal without unduly loading the device under test (DUT), while providing high offset to allow DC power/voltage rail signal display on an oscilloscope with high gain.
Large Offset Range
+/-30V offset permits the DC signal to be displayed in the vertical center of the oscilloscope grid with a high-sensitivity gain setting (maximum +/-800mV dynamic range).
Low Attenuation and Noise
The probe attenuation is a nominal 1.2x coupled to the oscilloscope at DC 50 Ω. This keeps additive noise to a minimum, and makes it exceptionally useful with HDO oscilloscopes for lowest noise at highest sensitivity gain settings.
High DC Input Impedance
50 kΩ input impedance at DC effectively eliminates probe loading on the DC power/voltage rail and provides for more accurate measurements and signal fidelity.
4 GHz of Bandwidth
Provides maximum bandwidth for probing near the CPU, and the perfect match with the 4 GHz,12 bit WavePro 404HD when making power integrity measurements.
Wide Assortment of Tips and Leads
The RP4030 is supplied standard with solder-in and coaxial cables with MCX and U.FL PCB receptacle mounts. A browser tip is optionally available. Additional receptacles or leads may be purchased as accessories and left connected in circuit for easy connection of different signals during different tests or validation stages.
Optional Browser Tip
A 350 MHz browser tip is available as an accessory. This browser tip is a conventional transmission line probe with a "pass-through"" 0Ω resistor to achieve 50Ω tip impedance and 1x attenuation. When used with the RP4030, high DC input impedance is also achieved. The browser tip accessory is also provided with 450Ω and 950Ω resistors for use as a conventional 10x or 20x transmission line probe.
