Micsig DP1505

Micsig DP Series High-Voltage Differential Probe offers a bandwidth of 100-500 MHz and a maximum input voltage of 7000 Vpk. With a standard BNC interface, they are compatible with oscilloscopes of most brands. Features include one-button calibration, overload alarm, range power-off memory, dual voltage ranges, and a high-resistance, low-capacitance design to minimize loading. The probe delivers strong amplitude-frequency performance, and a high common-mode rejection ratio. Command-based programming enables automated testing. 5 MHz bandwidth-limit function helps suppress high-frequency noise, delivering clearer waveforms. Product appearance may vary by version without affecting performance or functionality.

Excellent Bandwidth Flatness

DP series features excellent bandwidth flatness. Within 300 MHz bandwidth, the gain/loss variation is small. It maintains the accuracy of signal test even in high-frequency bandwidth.

High Accuracy, High CMRR

igh input impedance and low input capacitance, minimized load effect, greatly improved the accuracy of the differential signal. High common mode rejection capability, able to meet floating measurements of large common mode voltage at high frequencies. CH1: @ 100KHz, 770.3V, output common mode signal amplitude 46.25mV, CMRR > 80dB

Low Noise

DP3003 test results: noise at full bandwidth is 477.3mVrms (100X).

5MHz Bandwidth Limit

When measuring FET switching frequency in most switching power supplies, DP probe effectively eliminates high-frequency noise. Quick Zero Short-circuit the test leads, press Zero button, the probe can be zeroed very fast. Dual Range Selection Improves signal-to-noise ratio, meet more test requirements. BNC Interface Standard BNC interface, work with any oscilloscope.

Overvoltage Alarm

LED flashes, buzzer "beeps" rapidly, indicating an over-range alert. Compact & Exquisite Much smaller than traditional differential probes.
