SLM2200


Dual Frequency Selective Level Meter

The SLM2200 uses powerful DSP analysis to deliver accurate measurements quickly and easily. Believed to be the only dual frequency selective level meter available, it simultaneously analyses for two independent frequency components. The noise rejection of the processing allows signals to be measured even when buried in wideband noise. True real-time processing (no missed data) with a selectable filter time constant allows measurements to be made even with varying signals. The isolation of the inputs allows connection of the SLM2200 in any environment up to 500V cat II.

The automatic tuning algorithm scans a frequency range for two frequency components. The SLM2200 then tunes the center of the passbands to the frequency of the two components present using a series of narrowing sweeps with increasing resolution. Once the frequencies have been determined, the magnitudes are monitored and displayed in real time.
Despite it's sophisticated measurement capability it is very easy to use. The versatile graphic display allows results to be viewed as graphs, multiple data values, or large single values as appropriate.
The generator on the SLM2200 uses high-speed direct digital synthesis (DDS) to provide a variety of waveforms.
The SLM2200 is designed, manufactured
& supported in the UK

Example display: SLM Scope

FSK applications

A typical application for the SLM2200 is in testing of FSK telemetry. Traditionally, to measure the frequency and magnitude of the two frequency components the transmitter would have to be forced to transmit all 'ones' or all 'zeroes' in turn, and the measurements made on signals significantly greater than the noise floor. Using the SLM2200, the signals may be measured for both frequency and magnitude of the two components simultaneously at the receiver without changing the transmitter, even if the signals are noisy.
TAF01 & TAF02


Transformer analysis

Transformer parameters often vary with operating conditions, particularly frequency. When testing a transformer with QuanteQ the conditions are continuously variable from 10mV to 10V peak (200mA peak current) and 100mHz to 2.4MHz. An automatic frequency sweep can be used to measure any ac parameter over a frequency range and the results may be viewed on screen, or printed out as tables and graphs. Also, QuanteQ can detect the frequency from the circuit under test so that the transformer parameters may be measured under actual operating conditions.

TAF01

TAF01 is designed for testing transformers with 2 or 3 windings. Relays within the base unit make the appropriate connections for the test to be made. The base unit accepts customized jigs with ZIF sockets for quick testing of standard transformers, or Kelvin clip leads (supplied), to connect the non-standard transformers. Using the RS232 port of QuanteQ , a PC may conduct a series of tests without any manual input; PC software, CommTEST, can test the measurements against pre-set pass/fail limits.

TAF02

TAF02 has two vertical probes to energise coils or wound transformers without cores. The number of turns of a single winding or turns ratio of two windings may be measured and a shortened turn may be detected by measurement of Q factor. Supplied with Kelvin Clips, test leads or small 'grabber' test leads.

LPA01, LPA400

Laboratory power amplifiers

LPA01 & LPA400 are the first in a range of amplifiers developed to provide high accuracy amplification in an industrial or laboratory environment.

The LPA range

The LPA range of power amplifiers from Newtons4th Ltd are robust and reliable for use in a variety of industrial and laboratory applications. Designed originally for use with the QuanteQ and Veqtor , they can also be used anywhere where there is a need to boost a signal either in voltage or current.

They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms, driving loads that may be capacitive, inductive or resistive.

Optionally, the DC component can be eliminated with ac coupling, or can be reduced with AC+(DC) coupling. To limit high frequency noise, the input bandwidth can be reduced with a linear phase, 2nd order, low pass filter for low frequency applications.

The amplifier gain is selectable from three precision gain settings.

LPA01

  • High frequency, high current testing of wound components.
  • High frequency excitation of servos and actuators up to 1A.

LPA400

  • High voltage, high frequency calibration.
  • Driving high voltage actuators (e.g. piezo) up to 400V.

Features

  • DC accurate and wide bandwidth
  • Switch selectable coupling options: AC, AC+DC or AC with reduced DC.
  • Switch selectable precision gain settings.
  • Switch selectable bandwidth.
  • High slew rate.
  • 1A continuous output current @ up to ¡Ó12V peak (LPA01).
  • ¡Ó400V peak, 50mA rms (LPA400).
  • ¡Ó180V peak, 100mA rms (LPA400B).
  • Unconditionally stable into any load.
  • Isolated from ground to prevent earth loops.
  • Robust metal enclosure

Will fit underneath QuanteQ or Veqtor to boost output capability.
