Frequency Response Analyzer Accessories
The N4L range of frequency response analyzers can be used in a wide range of applications, in reflection of this we have developed various accessories to enable accurate, reliable and convenient measurement.
Injection Transformers
N4L Injection Transformers – Feedback Loop Response Analysis | ||||||||||||||||||||||||||||||||||
![]() | The PSM1700 and PSM1735 feature ground referenced generators, as a result there is a requirement to isolate the injected perturbation signal from ground so that the feedback loop is not shorted to the ground plane. This action is performed by an injection transformer and N4L have designed numerous injection transformers to meet a range of frequencies and voltages.

LCR Measurement
IAI Kelvin Fixture | ||||
![]() | The N4L Impedance Analyzer range offers high accuracy, high frequency LCR measurement. To accompany the IAI and IAI2 we have developed an IAI Kelvin Fixture. This fixture features four contact plates providing true four wire impedance measurement.

BATT470m – EIS Interface (Electrochemical Impedance Spectroscopy) | ||||||||||||
![]() | The BATT470m electrochemical impedance analysis interface (EIS) provides an easy to use battery/cell impedance test platform for the electrochemical industry. Utilizing the highly accurate PSM3750 frequency response analyzer from N4L, the BATT470 provides impedance measurement of batteries/cells up to 200V DC.

![]() | The PSM2 Power Meter Adaptor is an isolation and attenuation accessory designed for use with the PSM1700, PSM1735 and PSM3750 Phase Sensitive Multimeters. This adaptor utilises toroidal transformers and calibrated burden resistors. The PSM2 provides isolation and fixed scaling factors enabling the PSM series frequency response analyzers to perform input power measurements on single phase low voltage power devices.

Current Measurement
N4L HFm High Frequency Current Shunts | ||||||||||||||
![]() | If external current measurement is necessary for impedance measurement, for example if a test setup utilising an LPA Laboratory Power Amplifier for signal generation is employed. The HF series shunts provide an accurate current sensing solution for many wideband measurement applications up to 20Arms. Utilising an innovative design that is unique to N4L, each shunt will maintain its specified resistance over a frequency range from DC to 1MHz without exhibiting the phase shift normally associated with resistive shunts.

AC Current Clamps | ||||||||||||||||||||||||||||||||
|
As an alternative to selecting an HFm current shunt for external current measurement in impedance applications is our AC Current Clamp range. These clamps provide current measurement up to 3,000A (P32-UE) with an upper bandwidth of 15kHz (SMUB), providing accurate measurement of an AC signal over a wide bandwidth. Typical applications include impedance measurement of electrochemical cells where high DC current bias is present, the AC responding current clamp will reject the DC bias current and reliable accurate measurement of the AC perturbation current is recorded.
