Product Information
The Tektronix 2247A 100MHz analog oscilloscope enables you to monitor signals from your electronics equipment. This unit has a Benchtop form factor and features a powerful bandwidth of 100MHz. Other functions included with the Tektronix 2247A analog oscilloscope are a 34dB channel isolation, four channels, and a rise time of 3.5 NS. The Tektronix 2247A oscilloscope features an easy-to-read analog output graph that indicates a number of displays, including the volts, fall, rise, frequency, width, and time of an electrical signal. The 2247A 100MHz analog oscilloscope was brought to market by Tektronix in 1989, and has a number of user-friendly features to help increase productivity, such as the built-in voltimeter, integrated counter and timer, time and voltage cursors with CRT readouts, and auto setup. An oscilloscope, such as the Tektronix 2247A, is an electronic test instrument that allows the observation of constantly varying signal voltages. This is usually shown as a two-dimensional plot with one or more signals as a function of time. There are other signals, such as vibration and sound, that are converted and displayed. The first analog sample of signals measuring over 100 MHz was made possible by Tektronix in 1960. This Tektronix oscilloscope is used to observe changes in electronic equipment signals over time, in such a way that time and voltage describe a shape that is continually graphed against a calibrated scale. Observed waveforms are analyzed for such properties as frequency, rise, amplitude, distortion, time interval and others. Modern digital instruments calculate and directly display these properties. Original instruments required manual calculation of these values by measuring waveforms against scales that were built into the instrument’s screen. As well as the basic instrument, most analog oscilloscopes are supplied with a probe to test equipment. Oscilloscopes, as with all practical instruments, do not respond equally to all input frequencies. The range of frequencies the Tektronix 2247A 100MHz analog oscilloscope can display is what is referred to as its bandwidth. Primarily, bandwidth refers to the Y-axis, although X-axis sweeps have to be quick enough to show the highest frequency waveforms. The instrument’s probe connects to any of its inputs and typically features a resistor of 10 times the unit’s input impedance. This results in an attenuation factor of .1, but it helps to isolate the capacitive load given from the signal being measured. The simplest and earliest analog oscilloscopes are comprised of a cathode ray tube, a timebase, a power supply, a vertical amplifier, and a horizontal amplifier. Analog oscilloscopes have several advantages over other types of scopes, such as the scope’s intensity and focus control, which is adjustable to reveal a sharper and more legible display. As well, an analog scope features a phosphor-based display that provides a brighter trace during occurrence of signal features. This capability is also known as intensity grading, and it helps the operator to easily distinguish signal details. The Tektronix 2247A 100MHz oscilloscope is the perfect choice for anyone wishing to use an analog scope to measure the signals from their equipment.Product Identifiers

Tek 2247A High performance 100MHz scope
the 2247A is the final stage in the analog 22xx series from Tek, and has a real direct reading 200Mhz counter tied to channel 1, along with a multi-mode DMM. In addition, it has 4 channels (2 with reduced controls), dual timebases, and my personal fave (taken from the Philips/Fluke combiscopes), AUTOSET. A very nice combination of powerful features. The downsides are these: very hard to work on power supply (sandwiched in the middle with a fault prone fan), and many flat cables that are easily damaged with bad handling. the unit cannot be run with the power supply accessible, making some work very hard. I also had some trouble with sticky buttons (rubbing on the front pane overlay), but that is fixable. If you can accept the increased service issues, it is a very powerful scope, without the many custom hybrids that haunt the 2400 series. oddly, the counter just has an ordinary crystal timebase, with a very coarse adjustment. I think it would have really benefitted from a simply TCXO for a few dollars more. thermal timebase drift is significant, and hard to adjust.Bestätigter Kauf: JaArtikelzustand: Gebraucht

It is good equipement
You must remember that this oscilloscope it has AUTO SETUP. If you have a low cost digital oscilloscope, and you want to see better the waveform, you must buy it, and compliment your digital oscilloscope. If you are a hobbyist of electronic, and doesn't need measures how Vrms, FFT or complex measures, for example power electronics, it is your oscilloscope. The digital oscilloscopes low cost that they have low sample rate, they don't show the waveform how must be.Bestätigter Kauf: JaArtikelzustand: Gebraucht

Tektronix 2247A 4 Channel 100 MHz Oscilloscope + two probes + power cord
Tektronix makes excellent Oscilloscopes which seem to last forever. I have used their scopes for 50 years. Everything about this scope operates correctly. The scope has not been abused nor does it need any service. I will calibrate it myself.Bestätigter Kauf: JaArtikelzustand: Gebraucht

Tektronics 2247A Oscilloscope
Tektronics 2247A Oscilloscope fits my needs nicely. It is a bit bulky for my work desk, but suits the requirements. Works good, although it has taken me a bit of time to understand the functions correctly. It may be old, but does a nice job.Bestätigter Kauf: JaArtikelzustand: Gebraucht

Comes on but nothing works!
The device comes on but nothing works. It does come on. Screen is bright. I had to do some work to it to get it to come on. So it is in not good working order! I am not sure what is required/ how much work involved to make everything start working, like it's supposed to?Bestätigter Kauf: JaArtikelzustand: Gebraucht
