Need a calibration standard but not sure how much to spend? This guide compares four very different options, from a $13.72 reference board to a $1,999 phasing voltmeter kit.
The BDS PP-131 is a $275.50 open-box spectrum display with stereo input and adjustable display modes. The tested Ivie IE-30A/IE-30B pair costs $650.00 and adds a noise generator. See which fits your signal-analysis bench.
The RIDGID CA-25 makes it easier to see inside walls, pipes, and machinery without tearing things apart, and it lists at $49.99. A used listing and a 480x234 display are the trade-offs to weigh.
Compare the Klein Tools ET600 and Amprobe MegaTest 1 AMB-45 insulation resistance testers. This head-to-head covers price, condition, included accessories, and key features to help you pick the right one.
Compare four used Mitutoyo BHN506 CMM replacement parts across the $399 to $1,998 price range, from calibration master ball to axis servo motor, with recommendations for each failure mode.
The HoldPeak 3-in-1 packs a 50 MHz handheld scope, multimeter, and signal generator for $79.99. The Siglent SDS804X HD offers four 70 MHz analog channels and optional mixed-signal expansion for $461. Which one is the right fit?
A 50MHz handheld oscilloscope multimeter signal generator at $79.99 or a 150MHz two-channel digital storage oscilloscope at $370.50? Here is how to choose based on portability, bandwidth, and bench workflow.
Comparing the Aaronia HF 6080 PC-based spectrum analyzer with the Agilent N9010A EXA benchtop unit. Two very different prices, two very different conditions - find out which RF analyzer suits your bench.
The FNIRSI 2C53T is a $64.50 portable dual-channel scope with a built-in multimeter and signal generator. The Tektronix TDS220 trades portability for 100 MHz bandwidth and 1 GS/s sampling at $149.99. Use this head-to-head to pick.
Deciding between the 16MP VMS16M35-Wifi Industrial Camera and the 1600X Zoom 8LED USB Microscope? The camera costs $131.00 and offers HDMI-compatible and USB output; the USB microscope costs $15.83 and packs continuous zoom and 8 LEDs. Here's how they compare for microscope lab imaging.
A $225 4-in-1 oscilloscope and a $36,500 signal source analyzer serve very different needs. Compare bandwidth, frequency range, and intended use to see which one fits your bench.
A used 100 MHz Tektronix and a more expensive 4-in-1 FNIRSI with signal generation and spectrum analysis: choose the lower-cost scope or the multi-function bench tool.
Weighing a $199 portable TinySA Ultra+ ZS407 against a $3,950 used Rohde & Schwarz FSU, this head-to-head helps you choose between portability and advanced signal generation.
This head-to-head weighs the $225 FNIRSI DPOS350P 4-in-1 oscilloscope against the $4,111 Agilent N9010A EXA, an as-is RF analyzer with a 9 kHz to 7 GHz range and reported faults.
Compare the affordable FNIRSI 2C53T handheld scope with the Tektronix TDS 380 bench oscilloscope. Which used two-channel digital scope fits your budget and bench?
Comparing the Hantek DSO2000 and Digilent Analog Discovery 2? The Hantek brings a faster 1 GSa/s sampling rate and a built-in waveform generator, while the Digilent pairs 14-bit resolution with WaveForms software at a lower listed price. Here's how to choose.
The HAYEAR 4K 51MP industrial camera brings high-resolution HDMI capture in a camera-style package, while the TriL110 2K digital microscope bundles a 10-inch screen, triple-lens switching, and coin-focused viewing. Here's how to choose based on price, condition, and intended use.
A used 400 MHz benchtop workhorse and a 30 MHz USB scope with 14-bit resolution go head-to-head. See how price, bandwidth, sampling, and workflow decide the right oscilloscope for you.
Two used Agilent signal analyzers anchor opposite ends of the price scale. The N9320B delivers a 9 kHz to 3 GHz RF spectrum analyzer for $1,200, while the E5052B is a 10 MHz to 7 GHz signal source and phase noise analyzer for $36,500. Here's how to decide which one matches your bench work.
The FNIRSI 2C53T is a handheld dual-channel scope with a built-in multimeter and signal generator; the Siglent SDS804X HD is a 4-channel mixed-signal scope with 70 MHz bandwidth. We compare them to help you pick the right one for your work.
