Micsig DP1500 Differential Probe – 3.5ns Rise, 1500V, 100MHz

Description

Product Overview

The Micsig DP1500 is a high‑voltage differential probe engineered for demanding electronic test environments. Powered by Micsig’s proprietary SigOFIT technology, the probe delivers an exceptionally low noise floor and industry‑leading common‑mode rejection, ensuring that even the smallest signal variations are captured accurately. With a rise time of just 3.5 ns, the DP1500 can track rapid transients across a 1500 V isolation range, making it suitable for high‑speed digital, power electronics, and RF applications. Its bandwidth of 100 MHz provides ample headroom for most modern oscilloscope measurements, while the dual attenuation settings of 50X and 500X give users flexibility to adapt to a wide variety of signal amplitudes.

Physically, the probe measures 10.08 × 6.34 × 3.03 inches and weighs only 2.2 lb, offering a compact form factor that is easier to handle than many competing differential probes. The probe includes a standard BNC interface, guaranteeing universal compatibility with any oscilloscope that supports BNC connections. The kit also features an over‑range alert system composed of an LED indicator and an audible buzzer, providing immediate feedback when the probe exceeds its safe operating limits. This safety feature helps protect both the instrument and the user from accidental over‑voltage exposure.

Usage

The DP1500 excels in a variety of testing scenarios. In a laboratory setting, it is ideal for characterizing high‑speed digital logic families, such as LVDS, CML, and HSTL, where precise timing and low jitter are critical. Field engineers can rely on the probe for power‑module diagnostics, including monitoring gate‑drive waveforms, switching transients, and fault analysis in high‑voltage converters. Its robust construction and compact size make it suitable for on‑site troubleshooting of automotive power‑train components, renewable‑energy inverters, and industrial motor drives. The probe’s 1500 V isolation rating also enables safe measurement of floating circuits and isolated power supplies without risking damage to the oscilloscope.

Because the DP1500 works with any oscilloscope that has a BNC input, it integrates seamlessly into existing test setups, reducing the need for additional adapters or specialized equipment. Whether you are a seasoned test engineer, a research scientist, or a hobbyist building high‑frequency prototypes, the DP1500 provides the accuracy and reliability required to capture fast, high‑voltage signals with confidence.

FAQ

What oscilloscope bandwidth is required to fully utilize the DP1500?

The probe is rated for 100 MHz bandwidth, so an oscilloscope with at least 100 MHz bandwidth will allow you to capture the full frequency content of the signals you measure.

Can the DP1500 be used with differential measurement setups?

Yes, the DP1500 is a true differential probe and can be used to measure the voltage difference between two points while rejecting common‑mode noise, making it ideal for floating or isolated circuits.

How does the over‑range alert work?

When the input voltage exceeds the probe’s safe operating range, an LED lights up and a buzzer sounds, providing immediate visual and audible warnings to prevent damage.

Is the probe compatible with high‑impedance inputs?

The DP1500 is designed for standard 1 MΩ oscilloscope inputs, but its low input capacitance also makes it suitable for high‑impedance measurement scenarios.

What warranty does Micsig provide?

Micsig offers a one‑year limited warranty covering manufacturing defects, along with access to calibration services to maintain probe accuracy over its lifespan.
