Can I get Square Wave and Sine Wave together?

BNC | FAQ | Model 625/630/632 | Frequently Asked Questions (...
When the SIG OUT is providing sine waves, the SYNC OUT provides a signal that is high when the sine wave is positive and low when the sine wave is negative.

What is this 'sine wave'?

Controversial TKD FAQ
In their forms the ITF practice a little up and down motion that adds power to their punching techniques. Generally it doesn't carry over to their sparring because adding the upward motion slows the technique and telegraphs what's coming. The downward motion is the same kind of 'sinking' technique many Chinese styles do, the idea being rooting to the ground and letting gravity help you add power. See similar questions...

What is a modified sine wave?

Power Inverters FAQ
To produce AC from 12 VDC a couple of steps or conversions take place inside the inverter. First step is the input voltage (12 volts) is increased to 145 VDC. Step two, the 145 VDC is converted to 110 VAC by using advanced MOSFET transistors. The resulting AC output from this conversion is called a "modified sine wave". It looks like a squared off sine wave. Some appliances do not work well or not at all with a modified sine wave. See similar questions...

What is the difference between sine wave and modified sine wave?

FAQ Answers
Alternating current (AC) has a continuously varying voltage that swings from positive to negative. This has great advantages in power transmission over long distances. Power from your power company is carefully regulated to be a perfect sine wave, because that is what naturally comes out of a generator, and also because sine waves radiate the least amount of radio power.

How do I know if I need a sine wave, or if I can live with a modified sine wave?

FAQ Answers
The following gadgets work well with a modified sine wave: computers, motor-driven appliances, toasters, coffee makers, most stereos, ink jet printers, refrigerators, TVs, VCRs, many microwave ovens, etc. Appliances that are known to have problems with the modified sine wave are some digital clocks, some battery chargers, light dimmers, some battery operated gadgets that recharge in an AC recepticle, some chargers for hand tools (Makita is known to have this problem).

What is the difference between Modified Sine & Pure Sine Wave Inverters?

DC AC Power Inverters - F.A.Q's
If your equipment can accept some voltage fluctuation, consider a modified sine wave inverter. These inverters provide mobile power at a more affordable price and come in a full range of sizes. If you want to run your equipment exactly to the manufacturer’s specifications, choose a true sine wave inverter. With true sine wave, motor loads start easier and run cooler.

Do I need Modified Sine Wave, or Pure Sine Wave?

Inverter FAQ - DonRowe.com - Frequently Asked Questions abou...
a) Output voltage wave form is pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity. c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines. e) Reliably powers the following devices that will normally not work with modified sine wave inverters: We carry a full line of Pure Sine Wave Inverters here at DonRowe.

Is the AC output of the PV Powered inverter a pure sine wave output?

PV Powered
Grid Tied inverters can only convert the available energy from the DC solar array. The available power from the solar array is dependent on temperature and irradiance, which vary significantly from moment to moment. The name plate rating of your solar array is based on Standard Test Conditions performed in a laboratory and are not representative of a system's expected daily peak performance. See similar questions...

The displayed sine wave signal looks choppy. Can I smooth the shape of it?

B2 Spice AD FAQ
Yes, using the Step Ceiling parameter in the transient simulation set-up window. The shape of the curve is influenced by the TMAX parameter. You can set the TMAX parameter as approximately 1/16 of period of a voltage or current source signal. See similar questions...

What is a wave?

FAQ
A wave is a traveling disturbance that moves energy from one location to another without transferring matter. Oscillations in a medium or material create mechanical waves that propagate away from the location of the oscillation. For example, a pebble dropped into a pool of water creates vertical oscillations in the water, while the wave propagates outward horizontally along the plane of the pond. See similar questions...

My question is about WAVE (or gtkwave). Is there a WAVE FAQ?

What is a standing wave?

FAQ
A standing wave occurs when a continuous set of waves reflect off a surface and overlap each other. If the frequency is set just right for a perfect overlap of the initial and reflected waves, the wave will seem to stand still. Two distinct sections on a standing wave become evident. Sections that stay still are called nodes and sections between nodes that move up and down dramatically are called antinodes. See similar questions...

What is the largest wave recorded at the FRF?

WebBanner_newSlogan_thin
The largest wave recorded by the facility was recorded offshore at 8.1 meters (26.6 ft) during hurricane Isabel, September 18, 2003. Click here for more pictures. See similar questions...

Why is there no 'Wave 2/3' device?

FAQ
Wave 0/1', 'Wave 4/5', 'Wave 6/7', 'Wave 8/9' are the only wave devices available for WinMM / DirectSound applications. They are routed to the corresponding FxBusses, that is, 'Wave 0/1' is routed to 'stereo' mix which goes to 'front' output by default, 'Wave 4/5' is routed to front only, 'Wave 6/7' is routed to rear only, 'Wave 8/9' is routed to center and subwoofer. See similar questions...

Do you wave magic wands?

FAQs about Y Dynion Mwyn - Welsh Faerie Witchcraft
Well, we do have wands and use them during certain rituals. My garden pruners are one of my major magical tools, because I do a lot of work with herbs and with plants. I carry them everywhere. Im always using them for something, for snipping this or pruning that or taking a little slip of this to propagate. My drum is a very important magical tool, because its a great way to create energy in a group and to bring the energy of a group together. See similar questions...

What determines the velocity of a wave?

FAQ
The velocity of a wave depends upon the material or medium in which it is traveling. When a wave enters a new medium, the elasticity and density of the medium may cause a change in the velocity of that wave. Typically, the denser and more elastic the medium, the faster the wave will travel. See similar questions...

What is the best clothing for hot weather or a heat wave?

CDC Extreme Heat | Frequently Asked Questions
Wear as little clothing as possible when you are at home. Choose lightweight, light-colored, loose-fitting clothing. In the hot sun, a wide-brimmed hat will provide shade and keep the head cool. If you must go outdoors, be sure to apply sunscreen 30 minutes prior to going out and continue to reapply according to the package directions. Sunburn affects your body’s ability to cool itself and causes a loss of body fluids. It also causes pain and damages the skin. See similar questions...
