High performance power analyser The HA1600 is a high speed, high accuracy AC power analyser for single phase supplies of up to 16 Amps rms. The supply to be measured is connected via a dedicated input cable independently of the supply to the instrument. The output to the load is via a front panel mounted 'standard' mains connector. A wide range of power connectors is available including most European National types. The HA1600 can measure Watts, VA, Volts rms, Volts peak, Amps rms, Amps peak, Crest factors, THD, Power factor, Frequency and Inrush current. The large display can show multiple parameters simultaneously along with graphical representations of voltage and current waveforms. Dual 16 bit Analog to Digital converters continuously sample both voltage and current and give a wide dynamic range. A fast Digital Signal Processor gives the performance needed for continuous real-time analysis of the data. Advanced algorithms yield accurate results, using extended precision or floating point arithmetic wherever necessary. Compliance-quality harmonics analyser The HA1600 has been designed to make harmonics measurements both quick and simple. It measures harmonics from the 1st to the 40th and updates the display in real time. It is suitable for pre-compliance measurements using a normal mains supply and is capable of full compliance measurements to EN61000-3-2 in conjunction with a suitable power source (such as the AC1000). Capabilities include continuous monitoring of the supply voltage, continuous comparison to harmonic limits and timed test sequences with analysis of fluctuating harmonics. Compliance-quality flicker meter The HA1600 has the capability to operate as a compliance quality voltage variation and flicker meter in conformance with EN61000-3-3 and EN61000-4-15. Flicker severity can be measured in terms of Pst and Plt while simultaneously performing full analysis of voltage variations, including the calculation of the maximum value dmax, the difference between steady states dc and the change characteristic d(t). For pre-compliance testing, a current measurement method can be used, rather than voltage measurement, to eliminate the need for a clean power Generator and a reference impedance. A full range of interfaces A parallel printer Interface is included, for record keeping and archiving, and also a high speed RS-232 Interface is provided for use with either a printer or remote control Software running on a PC. The HA1600A also has a USB port for use with the HA-PC Link Plus Software. The internal Software of the instrument is stored in flash memory and can be updated through the serial port as the requirements of the measurement standards evolve. HA1600 and HA1600A The two versions of the instrument are in different cases, with slightly different front panel layouts. The HA1600A has a USB port. In all other respects the operation and performance of the two types is identical. Both use the same firmware, and this manual applies to either type if fitted with firmware version 2.80 or late

This synthesised programmable arbitrary waveform Generator has the following features: • 1, 2 or 4 independent arb channels • Up to 40MHz sampling frequency • Sinewaves and square waves up to 16MHz • 12 bit vertical resolution • 64k points horizontal resolution per channel • 256k point non−volatile waveform memory • Waveform linking, looping and sequencing • Interchannel triggering, summing, modulation and phase control • GPIB and RS232 interfaces The instrument uses a combination of direct digital synthesis and phase lock loop techniques to provide high performance and extensive facilities in a compact instrument. It can generate a wide variety of waveforms between 0·1mHz and 16MHz with high resolution and accuracy. Arbitrary waveforms may be defined with 12 bit vertical resolution and from 4 to 65536 horizontal points. In addition a number of standard waveforms are available including sine, square, triangle, ramp and pulse. Arbitrary waveforms may be replayed at a user specified waveform frequency or period, or the sample rate may be defined in terms of period or frequency. Extensive waveform editing features between defined start and end points are incorporated, including waveform insert, point edit, line draw, amplitude adjust and invert. More comprehensive features are available using the arbitrary waveform creation Software supplied. This is a powerful Windows−based design tool that enables the user to create waveforms from mathematical expressions, from combinations of other waveforms, freehand, or using a combination of all three techniques. Waveforms created in this way are downloaded via the RS232 or GPIB Interface. Up to 100 waveforms may be stored with the length and name specified by the user. Waveforms may be strung together to form a sequence of up to 16 steps. Each waveform may have a user defined repeat count from 1 to 32768. All waveforms can be swept over their full frequency range at a rate variable between 30 milliseconds and 15 minutes. Sweep can be linear or logarithmic, single or continuous. Single sweeps can be triggered from the front panel, the trigger input, or the digital interfaces. A sweep marker is provided. Amplitude Modulation is available for all waveforms and is controlled from the previous channel or from an external Generator via the MODULATION input socket. Signal Summing is available for all waveforms and is controlled from the previous channel or from an external Generator via the SUM input socket. All waveforms are available as a Triggered Burst whereby each active edge of the trigger signal will produce one burst of the carrier. The number of cycles in the burst can be set between 1 and 1048575. The Gated mode turns the output signal On when the gating signal is true and Off when it is false. Both Triggered and Gated modes can be operated from the previous or next channel, from the internal Trigger Generator (0.005Hz to 100kHz), from an external source (dc to 1MHz) or by a key press or remote command. Any number of channels can be phase locked with user defined phase angle. This can be used to generate multi−phase waveforms or locked waveforms of different frequencies. The signals from the REF IN/OUT socket and the SYNC OUT socket can be used to phase lock two instruments where more than 4 channels are required. The Generator parameters are clearly displayed on a backlit LCD with 4 rows of 20 characters. Soft−keys and sub menus are used to guide the user through even the most complex functions. All parameters can be entered directly from the numeric keypad. Alternatively most parameters can be incremented or decremented using the rotary control. This system combines quick and easy numeric data entry with quasi−analogue adjustment when required. The Generator has RS232 and GPIB interfaces as standard which can be used for remote control of all of the instrument functions or for the down−loading of arbitrary waveforms. As well as operating in conventional RS232 mode the serial Interface can also be used in addressable mode whereby up to 32 instruments can be linked to a single PC serial port.
