Tektronix TPS2012B

Performance You Need at a Price You Can Afford

The Tektronix TPS2012B 100 MHz, 2 Channel, 1.0 GS/s Digital Storage Oscilloscope offers a distinctive range of capabilities in an oscilloscope with controls and menus you will find familiar and easy to use. The Tektronix TPS2012/B 100 MHz, 2 Channel, 1.0 GS/s Digital Storage Oscilloscope with Isolated Channel technology provides isolation from ground and isolation between channels allowing you to take measurements with less worry about damaging circuitry. Battery power comes standard, making it a natural choice for field applications. For work on power electronics, optional software integrates commonly needed power system measurements into the instrument, speeding up power analysis and troubleshooting.

Make Floating and Differential Measurements – Quickly, Accurately, Affordably

Unintentionally grounding a circuit under test is a common cause of poor measurement results and circuit damage. Connecting two or more grounded probes can cause ground loops, and if the current is high enough can result in ruined components and equipment. Most importantly, taking floating measurements without the proper instruments and probes can pose a safety hazard.

Tektronix Isolated Channel technology simplifies floating measurements. Unlike ground-referenced oscilloscopes, the Tektronix TPS2012-B input connector shells are isolated from each other and from earth ground. Within the specified 600 VRMS maximum float voltage, Isolated Channel technology keeps current from flowing between the Tektronix TPS-2012/B input BNC shells or from any BNC shell to earth.

Different passive probes are available, depending on your application. With the included Tektronix TPP0201 passive probes, the Tektronix TPS-2012/B can measure up to 400Vp-p. However, to meet the safety rating of the Tektronix TPP0201, the reference lead of the probe must be maintained within 30VRMS relative to ground. Because of this, the Tektronix TPP0201 probe is well suited for working on digital and analog circuits in which the maximum voltage never exceeds 30VRMS.

Measurements on power conversion electronics usually require probes with higher voltage ratings. Tektronix offers two passive probes with insulation systems specifically designed for making floating measurements. Optional P5122 probes, when coupled with the Tektronix TPS/2012-B, are suitable for making measurements on 480 VRMS devices in Category II environments, with a maximum float voltage of up to 600 VRMS relative to earth ground. With the optional P5120 probe the Tektronix TPS:2012:B can measure up to 800Vp-p, with a maximum float voltage within 600VRMS of ground. With the optional P5120 probe the Tektronix TPS 2012 B can measure up to 800Vp-p with a maximum float voltage within 600RMS of ground. The Tektronix P5120 is the best choice for making AC-couple dripple measurements on high-voltage DC power supplies. Please see "Characteristics" for complete safety ratings and specifications.

Speed the Design and Test of Industrial Power Systems and Circuits

From mobile phones to industrial motor drives, power conversion technology has enabled significant advances in size, performance, and energy efficiency. But even the most basic task of viewing a converter’s input and output is complicated by multiple voltage references. Multiple references also make it challenging to view signals from control circuits and power circuits at the same time. Using ground-referenced oscilloscopes in these applications, without appropriate differential probes, can damage circuits and produce bad measurements. For debugging power conversion electronics, Isolated Channel technology reduces the risk of damage and unintended circuit interactions.

For performing power system measurements, Tektronix TPS2PWR1 power application software is available as an option for the Tektronix TPS2012-B 100 MHz, 2 Channel, 1.0 GS/s Digital Storage Oscilloscope. It provides advanced power measurements right on the oscilloscope, at an entry-level price.

For measurements on AC line voltage and for checking the impact on the power distribution system, the power application software shows harmonic content to the 50th harmonic, and provides phase, reactive power consumption, and power factor measurements.

Two power "bundles" are available, combining probes and measurement software. Each package combines four probes with the Tektronix TPS2PWR1 power application software, at prices that are lower than if purchased separately. The Tektronix TPS2PBND combines four P5120 20X passive, high-voltage probes with Tektronix TPS2PWR1 power application software. The Tektronix TPS2PBND2 combines four Tektronix P5122 100X passive, high-voltage probes with the power application software.
