Description
CE-DP1500V1.1
The Coffee Electronics active differential probe offers a >1.5 GHz bandwidth and is designed for high-precision differential signal measurements in high-speed, mixed-signal, and RF circuits. Its active input stage provides high impedance and excellent common-mode rejection ratio (CMRR), minimizing circuit loading and preserving signal integrity. The active differential probe is powered via its USB interface.
The probe connects natively to the eLABin1™ instrument series and is also compatible with any instrument that has SMA inputs (e.g., oscilloscopes, analyzers, or signal generators).
Main features
-
>1.5 GHz bandwidth (Normal/linear operation above 1.2 GHz, but USABLE up to 3 GHzNormal/linear operation above 1.2 GHz, but USABLE up to 3 GHz)
- DC-coupled operation for measurements starting at DC.
-
High-impedance active input with excellent CMRR
-
Dimming modes ×1 or ×10 (adapter required)
-
Maximum Operational Voltage: 1 Vpp (recommended)
-
Integrated LED lighting at the tip for precise visibility
-
USB interface module for power
-
Lightweight, protected and ergonomic design
- Measures differential signals and can also be used for single-ended measurements by connecting the negative input to ground.
-
Universal USB-A power input compatible with measurement instruments and standard 5 V USB power sources.
- Includes SMA-to-BNC, SMA-to-Type-N and SMA-to-TNC RF adapters for connection to oscilloscopes, spectrum analyzers, RF generators, network analyzers and eLABin1™.
