P100B Non-Switchable Passive Oscilloscope Probe, 100MHz, 1.2M Cable Length by Test Products International

Selecting the correct oscilloscope probe ensures accuracy and can improve the performance of your test instrument. TPI offers a wide range of high quality oscilloscope probes designed to meet the most demanding applications.

The IP series monolithic probes have switchable attenuation and are available in 60 and 250MHz. These probes are ideal for technicians that need a basic oscilloscope probe.

The slimline design P and SP series probes are available in fixed or switchable attenuation. These series of probes are perfect for the technician needing additional features such as replaceable cable and interchangeable probe tip. The compensation adjustment for these probes is located in the BNC to eliminate noise pickup.

TPI also offers three models of high voltage differential probes all with high common mode rejection, wide bandwidth, and fast rise times. Differential probes enable the viewing of signals not referenced to earth ground and provide better performance than a matched pair of single ended oscilloscope probes when measuring these types of signals.

Several important factors must be taken into account when selecting the proper probe.

• The probe should have sufficient bandwidth and rise time for the test instrument and application. Choose a probe with at least an equal bandwidth as the scope it will be used with. For best performance a probe with twice the bandwidth as the scope should be selected
• For oscilloscope probes, the input capacitance of your oscilloscope should be within the compensation range specification of the probe. In addition, if your oscilloscope has readout function, select a probe with this capability
• For differential probes, make sure the maximum differential voltage is adequate for your application and the common mode rejection specification meets the requirements of the tests being performed.

Features

• Attenuation: Ratio of the output signal to the input signal. Attenuation should remain constant decreasing by 3dB only as the frequency increases to the maximum bandwidth.
• Bandwidth: The maximum -3dB frequency that can be expected.
• Cable Length: Length of the cable from the end of the probe to the end of the connector. It is important to use a probe with just enough cable length for your needs. Long cables increase the capacitance and propagation delay of the probe.
• Compensation Range: The range a probe can be compensated to match the input capacitance of the test equipment it is being used with.
• IEC 1010: Probes with the IEC 1010 category rating have been designed for safety.
• Input Impedance: The total resistance and capacitance as measured at the tip of the probe. This specification is used to define the loading effect of a probe. At frequencies under 1MHz the input resistance of the probe will have the most influence. At higher frequencies the input capacitance will have the most influence.
• Max Input Voltage: The maximum voltage the probe can be used at.
• Max Differential Voltage: The maximum differential voltage that can be measured by a differential probe
• Readout: Probes with this capability are compatible with readout function oscilloscopes that automatically detect and display the attenuation factor of the probe.
• Rise Time: The time required for the leading edge of a pulse to rise from 10% to 90% of its final value.
• CMRR: Common Mode Rejection Ratio. A measure of a differential probes ability to reject any signals common to both test points in a differential measurement

Applications

• Use TPI Probes with Bench Top, Portable, Analog, and Oscilloscopes
• Logic signal and waveform tests
• Measure voice / data signals
• Analyze power quality
• Test motor control circuits

94461-07 Traceable® Extra-Large Digit Digital Timer with Calibration by Digi-Sense

Simple operation and memory function make this the ideal timer for repetitive timing applications. Intuitive three-button operation lets you quickly program and start your timing application. Automatic Bounceback™ memory function recalls your set time for repetitive timing operations. Also counts up in stopwatch mode. Built-in easel stand, pocket clip, and magnetic back give you multiple mounting options.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

• Get accurate, reliable measurements with included NIST-traceable calibration

Includes

One AAA battery and NIST-traceable calibration certificate with data.

81038 NexGO DX Smartphone Adapter Kit by Celestron

The NexGO Universal Smartphone Adapter is a great first step into the world of astroimaging or digiscoping. The NexGO provides you everything you need to capture sharp, detailed images and video.

NexGO fits any eyepiece from 25.4mm (1.0") to 44.45mm (1.75") in diameter, including most telescopes with 1.25" eyepieces, spotting scopes, monoculars, binoculars, and microscopes.

NexGO accommodates a wide range of smartphones including the latest devices from Apple, Samsung, and Google. The phone platform is fully adjustable and can fit any device–usually with the case still on. For older phones that are 5" tall or less, the NexGO includes a booster to ensure the fit with the device.

Precise Alignment

The NexGO sports rack and pinion X- and Y- fine adjustment knobs for precise alignment and it folds up to a smaller size for easy transport. Secure the NexGO smartphone adapter to your eyepiece by tightening the orange knob which will clamp the unit around the eyepiece.

Maximize your storage space when traveling or not in use, the NexGO smartphone adapter collapses to a compact configuration for easy transportation and storing.

NOTE: The X and Y adjustment racks come calibrated from the factory, but should you need to adjust them, go to the Support & Downloads tab and read our Tension Adjustment Guide for details.

Robust Construction

The secure platform stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body. The NexGO® will stand up to years of outdoor adventures.

Easy as Ever

Most adapters rely on you placing your phone perfectly on the platform and only offer limited adjustments. But NexGO® gives you the power to place your phone on the platform, center it over the eyepiece with the X and Y adjustment knobs until you have the entire field of view in your shot.

From start to finish, the process only takes about 30 seconds, including the time it takes to insert the phone into NexGO®, attach NexGO® to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs.

Switching phones, eyepieces, or optical instruments, requires only slight adjustments to re-center the camera over the new eyepiece. If multiple people want to capture a shot through your optic, NexGO's simple spring-loaded clamps make it easy to remove one device and replace it with another in seconds. NexGO® is the ideal solution for star parties and group bird walks where everyone wants their own shot of the action.

You can also switch your image from portrait to landscape simply by turning the padded eyepiece clamp and readjusting the X- and Y-axis to realign your phone with the eyepiece.

NOTE: NexGO® is compatible with telescopes, spotting scopes, binoculars, monoculars, and microscopes. NexGo works with most phone cases, but if you have an especially large phone case with built-in batteries or a folio-style case, you may need to remove it.

• A complete digiscoping solution: NexGO connects your smartphone to an eyepiece while the Bluetooth shutter release button helps you get a steady shot image every time.
• NexGO's design works with most optics including telescopes (with most 1.25" eyepieces), spotting scopes, binoculars, monoculars, and microscopes.
• Connect the remote shutter release to your phone via Bluetooth to take photos or start/stop video recording without unwanted vibration.
• Folds up for easy transport and storage.
• Charge your phone during use.
• Features two directional knobs (X-, and Y- axis) that perfectly align your phone's camera with the eyepiece in seconds.
• Stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body.
