![]() ![]() Virtually all of Arizona lies within the Colorado River drainage system. The zone marks the ecological border between the low deserts and the forested highlands it combines elements of both with, for example, the Spanish bayonet of the Sonoran Desert growing alongside the juniper characteristic of higher elevations. The Transition Zone bordering the plateaus comprises separated plateau blocks, rugged peaks, and isolated rolling uplands so forbidding that they remained mostly unexplored until the late 19th century. West and south of the rim, a number of streams follow narrow canyons or broad valleys south through the Transition Zone and into the Basin and Range Province. More than 200 miles (320 km) of the southern border of the Colorado Plateau is marked by a series of giant escarpments known collectively as the Mogollon Rim. Forest-clad volcanic mountains atop the plateaus provide the state’s highest points: Humphreys Peak, 12,633 feet (3,851 metres), in the San Francisco Mountains, and Baldy Mountain, 11,403 feet (3,476 metres), in the White Mountains. The incomparable Grand Canyon of the Colorado River provides the major exception to what has proved to be an area easily traversed. Although they are labeled mesas and plateaus, their ruggedness and inaccessibility have been exaggerated. Far less rugged than adjacent portions of the plateau in Utah, these tablelands in Arizona consist mainly of plains interrupted by steplike escarpments. The northeastern two-fifths of Arizona is part of the scenic Colorado Plateau. To Arizona’s two major physiographic divisions, the Colorado Plateau and the Basin and Range Province, geologists add the Transition Zone (or Central Highlands). Phoenix, situated in the south-central part of the state, is the capital and largest city. The Colorado River forms the boundary with California and Nevada. Its romantic reputation as a wild desert and a place of old-fashioned close-to-the-earth simplicity is at variance with the fact that after the 1860s the state’s economy became industrial and technological long before it was pastoral or agrarian.Īrizona is located in the southwestern quadrant of the conterminous states, bordered by California to the west, Nevada to the northwest, Utah to the north, New Mexico to the east, and the Mexican state of Sonora to the south. ![]() Such spectacular landforms as the Grand Canyon and the Painted Desert have become international symbols of the region’s ruggedness, yet Arizona’s environment is so delicate that in many ways it is more threatened by pollution than are New York City and Los Angeles. Arizona is well known for its waterless tracts of desert, but, thanks to many large man-made lakes, it has many more miles of shoreline than its reputation might suggest. Although widely reputed for its hot low-elevation desert covered with cacti and creosote bushes, more than half of the state lies at an elevation of at least 4,000 feet (1,200 metres) above sea level, and it possesses the largest stand of evergreen ponderosa pine trees in the world.

![]() ![]() NOTE: At this point the AWG output is not yet active. The Upload button will be highlighted while the data is being sent to the SmartScope. When you're done, hit the 'Upload' button, which will transfer the data to the SmartScope the AWG output. The AWG is configurable within these limits:ģ.3V (max amplitude will decrease accordingly!) You have to use the 'Upload function' button and check the Analog checkbox to activate the output (see further). TIP: Double-tapping the value will bring up the Numpad, which makes it much easier to specify accurate values Next, open up the Analog submenu and select the type of predefined waveform you want the AWG to generate:Ĭonfigure the amplitude, offset and frequency of the wave to be generated. In order to do so, first open up the main menu by tapping on the LabNation logo at the bottom-left of the screen, and expand the Generator menu. ![]() You can define your own waveforms (see below), or you can use one of the built-in signals which have been predefined in the SmartScope app. In the image above, you can see the AWG pin is surrounded by 2 ground pins, either of which you can use to connect to the other device.Ĭonfiguring the AWG using pre-defined waves The ground, so both devices have the same reference voltage.Please keep in mind that you always should bridge 2 wires between 2 separate devices. The signal generated by the AWG is presented on the 3rd-left pin on the bottom row of the AUX connector, as shown in the following image: 3.2 Define arbitraty waveform in Excel (.csv file upload).2 Configuring the AWG using pre-defined waves. ![]() |
