AHP Electronics is a small electronic products manufacturer company that concentrates its objectives to scientific research expecially in the astronomical field.
AHP Electronics products range from movimentation control, light and EM, mechanical detection sensors, processing tools and software as well.

There are two main categories of products that AHP Electronics is focused on at the moment: Astronomy and general Physics. This distinction was made due to the chances that astronomical oriented products offers to be applied into many fields of Physics.

Being projected into the future of amateur astronomy, AHP Electronics points to next frontiers of picture capturing and information elaboration, without scaring of partial observation the user should be able to obtain results from the elements gained. This is the motto of AHP Electronics.

HSP17 Photomultiplier Assembly


Price: 1200€


The HSP17 is a photomultiplier assembly composed by the PSU and socket board, the PMT itself and the insulation housing.
The HSP17 offers various PMT sensibility and spectral response possibilities.
The socket contains a voltage elevator, capable to supply PMTs of the 1.4/1.8 Kv range voltage supplies they need.
It supports russian tubes as the FEU17, the FEU39, FEU39A and similar products.
Its plug is compatible with the XC series cross-correlators and the AHP autocorrelators, including the special versions of the XC series.
It’s directly powered and connected to the processor by a single cable.
It has a front light entrance and can house a thermal cooler or specific adaptive optics.
The light entrance has a C-type threaded input, compatible with many optical path laboratory standards.
The specifications vary upon the PMT model and generally are:

  • RJ11 input plug
  • Alternate input supply voltage within 400vpp
  • FEU17, FEU39, FEU39A PMT possibilities
  • TTL active low output voltage
  • Socket on-board, with PMT substitution possibility
  • Light and electrically shielded housing
  • C-type threaded light entrance
  • Space within the PMT and the housing for custom cooling or mechanics design

      XC series telescope correlators


      The AHP XC series includes pulse counters, crosscorrelators and autocorrelators.
      The XC series accept TTL inputs with a maximum bandwidth of 200MHz.

      They support three operating modes:

      • Counter: each input pulses are counted within the sampling time and the total counts are reported by the serial packet.
      • Autocorrelator: to obtain the spectra of the pulse fluxes of each input.
      • Crosscorrelator: each input pulse is cross-correlated with other inputs’ pulses, with head and tail lag reports.

      Each input has an independent internal lines delay.
      Intensity correlation can be applied to photonics and interferometers, even optical and radio.
      AHP offers both optical and radio options for intensity interferometers with its radio detectors and PMT assemblies.

      AHP XC general specifications:

      • Up to 256 inputs for a maximum of 32640 baselines
      • Up to 4096 delay lines (8193 in cross-correlation mode) per channel
      • 16 tau multiplier channels, power factor of 2
      • 5ns minimum pulse width
      • Up to 200MHz bandwidth
      • Sampling rate up to 200Msps
      • Input resolution ranging from 1 bit to sampling bits
      • Autocorrelation multi-tau mode
      • Crosscorrelation multi-tau mode
      • Independent delay lines selection for autocorrelator and crosscorrelator modes
      • Direct reading of pulse counts, autocorrelation and crosscorrelation counts
      • Correlation counts on each baseline
      • TTL UART communication port
      • 57.6, 115.2, 230.4, 460.8, 2000 Kbaud sampling frequency
      • External line connector with independent switching pass-through on each input
      • RJ11 connectors standard for easy plug
      • Open Source C SDK
      • Open Source test GUI software

      4 channel 5A Power drive PM5



      Price: 259€

      The PM5 can drive 5 digital/PWM outputs reaching as high current as 5A per channel, switching in range of 0-5/0-24 volts at a maximum frequency of 10KHz.

      The PM5 is compatible with a single motor output of the GT1 at input end, while the output connector is compatible with the old standard DB9 port, so old astronomical mountings or motors are suitable for use.

      The PM5 also is well insulated, using an optocoupler as input stage, can be over/lower volted safely.

      It has these features and connectors:

      • RJ12 digital input connector, positive active
      • Coaxial supply voltage, center positive
      • DB9 output connector
      • High current and voltage: up to 5A/24V impulsive per channel
      • Optical input insulation

      GoTo mount controller GT1




      Price: 299€

      The GT1 is a stepper motor controller with goto functionality.

      The GT1 can be configured to drive any kind of mount, since it is capable to adapt on any gear ratio from the configuration software.

      You can change the gear ratio settings, microstep resolution, motor winding configuration and maximum goto/slew speed.

      Each motor winding can be supplied by the GT1 with a maximum of 1 Ampere current.The GT1 supports overvoltage up to 18v for tight motor grip.

      The GT1 is also compatible with the Skywatcher SynScan handset and EQMOD software, so you can use it standalone or by PC connection using software like SkyCharts, KStars or other software.It is also possible to drive the GT1 from the smartphone using INDI and KStars for Android.

      The precision in low speed, including autoguide and sidereal tracking, is 64 microsteps.The maximum speed has no limit, but must be appropriate to the load and weight of the telescope and the power of the engines.The configuration software can set motor parameters, go-to acceleration and maximum speed.

      It is equipped with these inputs/outputs:

      • SynScan Hand-set compatible input
      • Autoguider input
      • Stepper output
      • Right Ascension Stepper output
      • Declination Stepper output
      • 12v Power input
      Being compatible with the Merlin protocol it can be connected directly to the computer and driven by software like EQMOD.
      The precision in low speed, including autoguide and sidereal tracking, is 64 microsteps.

      The maximum speed has no limit, but must be appropriate to the load and weight of the telescope and the power of the engines.

      The configuration software – downloadable here – can set motor parameters, go-to acceleration and maximum speed.
