SigOFIT optical-fiber isolated probes: higher published specs than Tektronix IsoVu and Keysight, at a fraction of the price. Plus MICSIG oscilloscopes and current probes, from Pertech.
Pertech is the exclusive MICSIG distributor in Israel, supplying MICSIG's SigOFIT optical-fiber isolated probes, oscilloscopes and current probes to power electronics, automotive and R&D teams across the country.
SigOFIT is MICSIG's optical-fiber isolated probe. A laser carries both the signal and the power over fiber, giving an 85 kVpk common-mode range and CMRR of 180 dB at DC and 106 dB at 1.2 GHz (Gen 3). That makes it suited to fast high-side measurements on GaN, SiC and IGBT half and full bridges, where conventional differential probes struggle with common-mode noise. The Gen 3 series runs from 200 MHz to 1.2 GHz, and its BNC output works with any oscilloscope.
MICSIG also makes 12-bit high-resolution oscilloscopes (MHO and STO), tablet oscilloscopes up to 500 MHz (MDO, ETO, TO and the VTO for Android), automotive oscilloscopes, high-voltage differential probes, and AC/DC and Rogowski current probes. Through Pertech you get quotes in ILS with local invoicing, warranty handled in Israel, calibration and repair arranged through Pertech, some models in stock in Israel, and Pertech engineers to help you choose and set up.
On the makers' own published figures, MICSIG's SigOFIT Gen 3 offers more bandwidth (1.2 GHz), a higher common-mode range (85 kVpk), stronger common-mode rejection at high frequency (128 dB at 100 MHz) and twice the differential range (+/-5000 V) of the Tektronix IsoVu and Keysight PS0008A optically isolated probes.
And it costs a fraction of the price of those probes. Ask Pertech, the exclusive MICSIG distributor in Israel, for a SigOFIT quote in ILS.

Test conditions and tips differ between makers; check each data sheet for your measurement.
Yes. Pertech is the exclusive MICSIG distributor in Israel and sells MICSIG's SigOFIT optical-fiber isolated probes, oscilloscopes and current probes to customers in Israel.
SigOFIT is MICSIG's optically isolated voltage probe. A laser sends both the signal and the power over fiber, so the probe head needs no battery. The SigOFIT Gen 3 (MOIP series) runs from 200 MHz to 1.2 GHz with an 85 kVpk common-mode range, 180 dB CMRR at DC, 1% DC gain accuracy and noise as low as 0.3 mVrms.
When you measure fast signals that sit on a large, fast-moving common-mode voltage, such as the high-side gate or switch node of a GaN, SiC or IGBT half bridge. MICSIG specifies the SigOFIT Gen 3 at 122 dB CMRR at 200 MHz and 106 dB at 1.2 GHz, with input capacitance as low as 1 pF, so the common-mode noise and ringing that affect conventional differential probes are strongly suppressed.
Yes. MICSIG specifies a universal BNC output for SigOFIT, compatible with oscilloscopes of all brands, not only MICSIG's.
On the makers' published figures, SigOFIT Gen 3 reaches 1.2 GHz (IsoVu and Keysight PS0008A: 1 GHz), handles 85 kVpk common mode (both others: +/-60 kV), keeps 128 dB CMRR at 100 MHz (IsoVu: 100 dB; PS0008A: 65 dB with its best tip) and measures up to +/-5000 V differential (both others: +/-2500 V).
Yes. SigOFIT costs a fraction of the price of the Tektronix IsoVu and Keysight PS0008A isolated probes, while offering higher published specifications. Pertech, the exclusive MICSIG distributor in Israel, quotes in ILS.
Choose by bandwidth and voltage. SigOFIT Gen 3 comes in 200 MHz, 350 MHz, 500 MHz, 1 GHz and 1.2 GHz models, with interchangeable attenuator tips from +/-10 V to +/-5000 V. Gen 2 covers 200 MHz to 1 GHz. Pertech will help you match the model and tips to your circuit.
12-bit high-resolution oscilloscopes (MHO6, MHO3, MO3, MHO1 and the STO tablet), 8-bit tablet oscilloscopes (MDO, ETO, TO and the VTO for Android), and automotive oscilloscopes (AHO1, ATO, SATO, VATO).
The CP series high-frequency AC/DC probes (DC to 150 MHz for small currents, up to 500 Arms for high currents), the CP2100 low-frequency AC/DC probe, the ACP1000 AC clamp probe up to 1000 A, and the RCP series Rogowski probes up to 12000 Apk and 30 MHz.
Yes. Pertech quotes MICSIG products in ILS and invoices locally in Israel. Contact Pertech with the model or the measurement you need.
Pertech handles warranty for MICSIG products it supplies in Israel: you return the unit to Pertech, and Pertech deals with MICSIG. Pertech also arranges calibration and repair.
Some MICSIG models are kept in stock in Israel; others are ordered from MICSIG. Ask Pertech for the current lead time. Pertech engineers also help with setup and application questions after the sale.
