Kikusui’s new fuel cell impedance meter

Kikusui’s new fuel cell impedance meter KFM2030 is intended to enable the impedance characteristics of a fuel cell to be measured easily through the use of the AC impedance measurement method.

KFM2030 New Kikusui fuel cell impedance meterUsing the application software that comes with it, the meter can obtain impedance values at different frequencies by means of AC impedance measurement and display the obtained values in a Cole-Cole plot. With a low-power DC load (60 W) built in it, KFM2030 supports fuel cell load testing at up to 20 V, at up to 30 A.

Features Include:

  • Impedance of cells of up to 20V can be measured in the range of 10 mHz to 10 kHz. (The cell voltage can be read back as well in the 0 V-20 V range.)
  • Two constant current modes ranges for the load rating: 30 A and 5 A Load current setting resolutions of 1 mA (30 A range) and 0.1 mA (5 A range) are available, with maximum power consumption of 60 W.
  • Undervoltage protection, overvoltage protection, overpower protection, overheat protection, overcurrent protection, and line cut detection are supported.
  • The backlit LCD offers enhanced visibility.
  • Four types of measurement value can be chosen for display freely from R, X, | Z |, ? , V, and I.
  • Equipped with GPIB, RS-232C and USB interfaces as standard.
  • Impedance measurements can be made in the range of 10 mHz to 10 kHz as well on both primary and secondary cells.

Intelligent 4 Quadrant Bipolar Power Supply

Kikusui’s new PBZ Power Supplies enable polarity change without changing terminals. Just vary the output control to seamlessly pass through zero. Four quadrant operation allows the power supply to act either as a source or load.

Intelligent 4 Quadrant Bipolar Power Supply from KikusuiNot just power supplies, the PBZs are also high power function/arbitrary waveform generators with sine/square/triangular outputs and frequency (up to 100kHz) plus variable rise time (from 3.5uS). There are soft start/stop functions, ramp up/down, AC on DC and user programmable sequence function.

Currently two models (+/-20V/+/-20A) and (+/- 40V/+/-10A). Units can be paralleled for more current.

The PBZ series is a bipolar type DC regulated power source that can continuously change both + and – polarities passing through 0 without changing the output terminal.
By adopting a “Switching + Linear” system, the PBZ is able to realize both drastic weight reduction as well as high speed and low noise operation. Since operation covers 4 quadrants, power can be both supplied (source) and absorbed (sink).
The PBZ can also drive inductive or capacitive loads. The unit also equips a signal generator function which enables waveform and sequence creation. The PBZ is also capable of synchronized operation which is required for voltage variation tests, and it can also be expanded for large current applications through master-slave parallel operation.


  • Low ripple and noise (in CV mode)
    For the Ripple 2mVrms, Noise 20mVp-p (PBZ20-20)
  • Waveform generation function
    In addition to the basic sine, square and triangular waveforms, the PBZ series is equipped with a user-defined waveform generating function that can register up to 16 waveforms. It allows the amplitude, frequency, start phase, frequency sweep and square wave duty to be set as needed. The 16 user-defined waveforms can be freely edited, and the original created and edited waveforms can be registered and easily recalled for use. The sequence function allows each waveform to be set as a single step, and a maximum of 1024 steps can be set in the 16 programs.
  • Sequence function
    The basic sine, triangular and square waveforms, as well as the 16 user-defined waveforms, can each be set as a sequence step, allowing even complex sequences to be created easily. Sequences are composed of up to 1024 steps.This combination of steps forms a program, and the 1024 steps can be allocated and set in a maximum of 16 programs. When executing sequences, in addition to executing a single program, the script function also allows multiple programs to be combined and executed as needed.
    A script is a function that specifies the sequence and number of repetitions for the set programs. A maximum of 50 lines can be set in 1 script. 1 script can be set each for CV and CC mode.
    As shown in the figure, when Program 1 uses 8 steps, 1024 – 8 = 1016, the remaining 1016 steps can be allocated to the remaining 15 programs.
  • Synchronized operation function
    This function synchronizes the power output when a sequence is executed using multiple PBZ.It prevents time deviations from occurring even when a long sequence is executed.
  • A delay of up to 1µ s occurs at the start.
  • Parallel operation function
    This function expands the output current. It allows multiple units to be connected in parallel according to the required current. With 2 standard units of the same modeland the optional parallel operation kit, the user can easily complete the setup. Although up to 5 units can be operated in parallel, if 3 or more units will be used, please consult us.
  • This is a function unique to this product. Because the voltage is unipolar, this function is called “unipolar mode”. With unipolar power although the current flows in a single direction, in unipolar mode it is still possible to apply current in both directions (source and sink).
  • CV/CC selectable mode
  • Memory function
  • Protection functions (Over voltage/Over current/Over heat/Power limit)
  • Fine setting
  • Key lock
  • Remote sensing
  • Output voltage/current monitor
  • External voltage/resistance control
  • External signal input
  • Status signal output

RIGOL adds yet more value for EMC users of Spectrum Analysers with Pre-Compliance & Advance Measurement

Rigol Technologies, leading instrument manufacturer, now adds more value for EMC Pre-compliance / advanced users, by including a free firmware enhancement. RIGOL now packs even more capability into the advanced DSA1000 spectrum analysers so customers get EMI Filter and Quasi Peak Detector option as well as the advanced measurement kit as standard. This enhancement now allows users to perform their own EMC Pre Compliance tests up to 3 GHz. Users say the cost of a fully compliant EMC test instrument according to CISPR 16-1-1 will break the bank, and the find RIGOL’s solution to be only slightly shy of CISPR performance, so ideal for necessary pre-tests. DSA1030 and DSA1030A models are available with optional 3 GHz tracking generator and an optional VSWR bridge, so they can also be used as a scalar network analyser. A built-in pre-amplifier allows up to -148 dBm Displayed Average Noise Level (DANL), and with advanced standard functions like power measurement, Harmonic Distortion or TOI the DSA1030A analysers are ideal instruments for powerful and versatile high frequency measurements. The use of a digital IF, which is standard for all Rigol spectrum analysers, helps minimize errors due to filter switching and reference level uncertainties; display errors suffered by traditional analogue IF designs when they switch between log and linear amplitude are minimised too. Today’s new freebies, previously sold for £400+ and now added by Telonic, include EMI Filter & Quasi Peak Detector and the integrated Advanced Measurement Kit making the DSA1030A-TG the ideal choice for pre compliance tests of boards, devices and components. Customers can now troubleshoot and test designs on their bench without having to schedule and pay every time at a full compliance lab. Pre testing like this is increasingly popular with engineers to stay within the EU-wide regulations for EMC during the design phase and avoids very expensive re-designs, reduces development time and accelerates your time-to-market. Doug Lovell, Sales Director with Telonic Ltd adds “RIGOL has already proven advantages in countless DSA applications… these new offers mean even better price-performance for our RF/EMC clients.” Brand new offers and prices are also announced today by UK Distributor Telonic at and VSWR bridges can now be had with more functionality too.
