Everything for Electronics

New Products


Saelig Company, Inc., is now offering the Owon TAO3000 Series 2/4-channel 8/14-bit tablet oscilloscopes. These are handy, portable scopes that are especially suited for field use.

They offer 70, 100, or 120 MHz bandwidth and a 1GSa/s signal sampling rate, with a built-in 4-1/2 digit multimeter in the two-channel models. A huge 40MSa record length allows for deep investigation into glitches and other small signals.

An internal built-in 8000 mAh high-capacity battery allows for continuous operation of up to five hours. The 8” multi-point capacitive touchscreen makes for quick and easy parameter adjustment, with SCPI and LabVIEW support allowing external control.

The front panel also has conventional knobs and function buttons for direct control of the instrument, and with its pull-out feet, it can become a very useful compact benchtop oscilloscope taking up minimal space.

There are 10 models in the TAO3000 series with either standard eight-bit resolution or precise 14-bit resolution, which is necessary for seeing fine detail in signals being examined.The oscilloscopes provide 39 automatic signal measurements including: Period, Frequency, Mean, PK-PK, RMS, Max, Min, Top, Base, Amplitude, Overshoot, Preshoot, Rise Time, Fall Time, +PulseWidth, -PulseWidth, +Duty Cycle, -Duty Cycle, Screen Duty, FRR, FRF, FFR, FFF, LRR, LRF, LFR, LFF, Delay A→B , Delay A→B , Cycle RMS, Cursor RMS, Phase A→B , Phase A→B , +PulseCount, -PulseCount, RiseEdgeCnt, FallEdgeCnt, Area, and Cycle Area.

The Autoscale function enables the instrument to automatically set the trigger mode, voltage scale, and horizontal time display according to the input signal characteristics.

Multiple advanced triggers and bus decoding protocols are also provided.

The oscilloscope supports communications with a PC through USB, a LAN port, and also via optional Wi-Fi. The oscilloscope communication software provided allows users to store, analyze, and display the data, as well as for remote operation of the instrument.

The oscilloscope series also supports communications with an Android-based smart device via Wi-Fi for viewing the waveform synchronously or for controlling or adjusting the instrument.

The list of features include:

  • 2/4 Channels
  • 70 MHz-120 MHz Bandwidth
  • 1GSa/s Sample Rate
  • 8/14-bit Resolution
  • 40MSa Memory
  • 4-1/2 Digit Multimeter & Data Logger
  • 45,000 wfms/s Waveform Refresh Rate
  • Built-in 8000 mAh Battery for Five Hour Operation
  • 8” Multi-point Capacitive Touchscreen

This compact (10.63” x 7.52” x 1.9”; 3.75 lb) portable scope is ideal for field work where line power is not available or as part of a traveling toolkit for troubleshooting on location away from the lab.

Manufactured by specialist test equipment manufacturer Owon, the TAO3000 Series of tablet oscilloscopes are priced starting in the mid $500 range.

The new Electro-Harmonix Nano Pulsar variable shape stereo tremolo shrinks down their timeless Stereo Pulsar and boasts some modern updates. True to the original, the Nano Pulsar features an adjustable variable LFO waveshape that can be set to triangle, sawtooth, and square waveforms, and can be morphed into all shapes in between.

Push the Depth knob past its max setting (around noon) and the waveform starts to invert in on itself; you’ll have an inverted phase tremolo like no other. The Nano Pulsar also now features a Volume control to get the perfect level for your tremolo tone. Set it up in stereo to be tossed amongst the waves.

The Nano Pulsar takes tremolo beyond the ordinary and mundane. Equipped with a collection of tremolo-modulating waveforms and the option of operating in triangle or square wave modes, the Nano Pulsar is a tremolo/panner treasure chest.

In mono, it’s simply amazing, or, connect it in stereo to create shifting waves of sound that surround you and fill your space with weaving, pulsating energy.

For all its power, the Nano Pulsar’s layout is intuitive and using it is easy. There’s often a perceived volume drop with tremolo when the effect is engaged, so Electro-Harmonix included a Volume control.

It allows a player to fine-tune their output level when the effect is on. This is a very useful addition.

The Nano Pulsar’s Depth knob adjusts the amount of tremolo applied to the signal. Past maximum (around 1 o’clock), the modulation becomes asymmetric and warps the audio signal between positive and negative phase.

This creates a unique style of tremolo which sounds great alone or used in combination with other effects like the Oceans 11’s Shimmer patch to produce compelling synth-like sounds and textures.

The Rate knob provides a full range of speed adjustments for the tremolo or pan effect, and when you start to max out the Rate and Depth controls, you enter ring modulation territory for a surreal sonic joyride.

Unlock a world of advanced sound shaping and control. Create tremolo and panning effects that go from sublimely beautiful to downright shocking. The compact Nano Pulsar is a do-it-all go-to pedal for all things tremolo and panning.

The Nano Pulsar is equipped with a nine volt battery and can also be powered by an optional nine volt power supply, such as EHX’s 9.6 VDC-200 mA power adapter. The pedal is listed at $99.

Cal Test Electronics is now offering a new hook clip to further enhance your testing needs. Available either individually (CT4466-#) or as a black and red pair (CT4467), these rugged hook clips are rated to 1,000V CAT III, 5A when used in conjunction with similarly rated 4 mm sheathed banana plug leads.

The hook clip easily connects to the 4 mm sheathed banana plug leads of DMMs, differential probes, or other similar types of equipment.

The plunger style actuation facilitates quick connections while allowing limited exposed contacts, thus reducing unintentional shorts. The hook can accommodate conductors up to 2.5 mm in diameter.

The clip, at around five inches (12.6 cm) long, gives you the reach you want, plus the sizing needed to safely meet 1000V CAT III. These clips are still compact enough for those small, hard-to-reach circuits.

This boosted servo extension from ServoCity lets you control up to four servos over a CAT6 cable. This approach allows you to control your servos from a distance with the rock-solid connectivity of a wired setup. It can control up to four servos at once, making it useful if you need to tidy up the wiring on your project. It includes one sending board with case, one receiving board with case, and four servo extensions. Price is $24.99.


This ServoCity two-stage Viper Slide kit utilizes steel Viper Slides as the backbone of this very smooth and stable slide kit. The Viper Slides are steel, so that excellent strength and durability can be captured in a compact form factor.

Use the kit in any orientation, whether you’re reaching up or out. The maximum travel (difference between retracted and extended) is 488 mm (19.2”), while measuring only 384 mm (15.1”) tip to toe in the retracted state. Price is $119.99.


The Servo Power Node also from ServoCity can provide power distribution or isolation between your servos and other PWM controlled components from the board or boards that generate the PWM signals.

All the positive contacts of the Servo Power Node are tied together and all the negative contacts are tied together making it ideal for powering logic devices and servos from the same battery.

However, if electrical isolation is required, the positive wire should be removed or excluded from the connection(s) between the Servo Power Node and the logic controller(s).

The end of the board without an XT30 connector has plated thru-holes, so you can solder in an XT30 (MH-FC) connector to daisy chain boards that share common power. Price is $12.99.
