Differential probes

TR1007A high-voltage differential probes

TR1007A high-voltage differential probes are available for all major oscilloscopes in the market, converting a floating signal to a low-voltage signal at the ground level, making it safe and easy to display any reference ground level oscilloscope. The probe can be used at frequencies up to 70MHz for 700V voltage signals and has high common-mode rejection, making it an excellent choice for non-georeferenced, floating, or isolated measurements. Angstrom oscilloscope differential probes are ideal for power testing, switching power supplies, inverters, motor drive control, switching power supply development, maintenance and evaluation.

Features:
• Safe floating measurements
• No damage to the oscilloscope and device under test
• Strong anti-interference ability
• Audible and visual alarm function
• 5MHz bandwidth limit function selection
• Good common-mode noise rejection

Safe Floating Measurements

Differential probes can be used to directly measure multi-channel non-common ground circuits without fear of damaging the device or measurement system under test, and the oscilloscope is isolated from the signal under test with high impedance and no risk of electric shock.

The probe is safe to use

A common but risky practice is to disconnect the oscilloscope's power grounding wire, as floating measurements can generate dangerous voltages on the oscilloscope, and the user touching the instrument will be the shortest path to ground and be electrocuted.

CMRR performance upgrades

Common-mode rejection ratio (CMRR) refers to the ability of a differential probe to suppress any signal shared by two test points in a differential measurement. If the CMRR index of the differential probe is not good, the common-mode voltage will be added to the differential voltage, causing measurement errors.

The oscilloscope interface is compatible for use

The oscilloscope does not automatically recognize the attenuation ratio of other brands of probes, and the probe attenuation ratio needs to be manually set on the oscilloscope to prevent deviations in the measured values

Rise time test

The DS6104 outputs a fast-edge signal with a frequency of 1MHz, amplitude of 2Vpp, and a rise time of 600ps to the input of the differential probe via a cable.

Output noise test

Short the input of the probe and connect the output to the oscilloscope. Set the attenuation step of oscilloscope channel 1 to 5 mV/div, the scan time to 50 nS/div, and the input impedance to 1 MΩ.
