Are you developing electronics? Then this is an ideal tool for your lab: High-impedance probe

496,00  inkl. MwSt.

PicoSearch has developed an active and extremely high-performance probe head for general laboratory work. With a peak load current consumption of less than 0.3 pA (0-5 V), it does not stress the circuit during the measuring process. These probes have become an indispensable must in the development of power-saving circuits.

Description

In recent years, more and more emphasis is placed on low energy consumption of electronic circuits. Sensor technologies with a power consumption of less than 200nA at 3V are no longer a rarity. This is where developers with conventional oscilloscope probes reach their limits. In particular, a probe the measured values significantly falsified by its internal resistance, which is usually between 2 and 10 MΩ.

Unfortunately, “high-impedance” probes are hard to find in the market. That´s the reason for a difficult order and a high price.

Therefore, PicoSearch has developed an extremely high-impedance active probe for general laboratory work. With a load current consumption of less than 0.3pA (0 – 5V) it does not load the circuit during the measuring process.

These probes have become an indispensable part of developing power-saving circuits. That´s the reason we have built the High-Impedance probe in small line to support and make it available to our partner and customer.

Connection of the probe

The high-impedance probe is connected through the USB port to a standard 5V power source, ideally directly to the oscilloscope’s connector. Connect the probe to the USB port of the oscilloscope for direct power supply. 

WEEE-Nr.: DE48986370

Areas of applications

Signal measurement with extremely high-impedance connection.

Applications example

The measurement with the probe can be performed as usual with the probe. Alternatively, you can attach the included clamping hook to the probe to take measurements. The USB connection is used exclusively for the power supply of the probe. No data will be transferred via USB.

The high-impedance probe is connected through the USB port to a standard 5V power source, ideally directly to the oscilloscope’s connector. If there is no connection, use a suitable voltage source. The USB connection is used exclusively for the power supply of the probe. No data will be transferred via USB.
