Compare the used Tektronix TDS220 benchtop oscilloscope with the new HoldPeak Digital 3in1 handheld scope and multimeter. See which one matches your bench or field needs, from bandwidth to portability.
The FNIRSI DPOS350P offers higher bandwidth, a built-in signal generator, and a lower price, while the Siglent SDS804X HD brings four analog channels and an expandable mixed-signal platform. Here's how to choose.
The $225 FNIRSI DPOS350P packs a signal generator and spectrum analyzer into a 7-inch digital scope; the $195 Tektronix TDS 380 offers 400MHz bandwidth and 2GS/s sampling. Here's how to choose.
Choosing between the $225 FNIRSI DPOS350P 4-in-1 oscilloscope and the $4,850 Agilent N9010A EXA RF signal analyzer comes down to whether you need a ready-to-use bench tool today or are willing to take on a surplus repair project.
Choosing between the Aaronia HF 6080 and the Sencore FS74 Channelizer SR? This head-to-head compares a PC-based RF spectrum analyzer with a dedicated TV-RF channelizer to help you pick the right used unit.
The Agilent N9010A EXA is a surplus RF signal analyzer at $4,111 sold as-is with known errors, while the Agilent Keysight E5052B is a used signal source analyzer at $36,500. This head-to-head helps you decide which instrument fits your budget and repair tolerance.
The used Tektronix TDS220 and the open-box Digilent Analog Discovery 2 offer two very different scope workflows for nearly the same budget. This guide helps you pick the right one.
A $199 portable spectrum analyzer with a touchscreen and 32GB storage squares off against a $36,500 used lab-grade phase noise analyzer. Find out which signal spectrum analyzer matches your work.
Choosing between the Sencore FS74 TV-RF analyzer at $150 and the Agilent N9320B 9 kHz to 3 GHz spectrum analyzer at $1,200 depends on whether you need broadcast signal checks or general RF measurement.
Need a signal spectrum analyzer? The Agilent Keysight E5052B is a used 7 GHz unit at $36,500; the Agilent N9010A EXA is a $4,850 parts-only RF analyzer. See which fits your bench.
Choosing between the USD 36,500 Agilent Keysight E5052B signal source/phase noise analyzer and the USD 650 Ivie IE-30A/IE-30B spectrum analyzer with noise generator comes down to measurement depth versus a tested vintage pair.
Deciding between the portable HoldPeak 3-in-1 oscilloscope multimeter and the higher-spec Hantek DSO2000 series? This head-to-head compares price, bandwidth, and built-in tools.
The BDS PP-131 turns audio into a 31-segment spectrum display; the TinySA measures radio frequencies and doubles as a signal generator. This head-to-head helps you pick the right one for your workbench.
Choosing between a $39.98 TinySA and a $3,950 Rohde & Schwarz FSU comes down to whether you need vector signal generation or just a low-cost way to sweep signals. This head-to-head breaks down the trade-offs.
New Hantek DSO2000 with 1 GSa/s sampling and built-in 25 MHz waveform generator costs USD 199.97; used HP 54600B with 100 MHz bandwidth, front cover, and case costs USD 135.00. Here's how to pick.
A compact audio spectrum analyzer at $275.50 and a Rohde & Schwarz FSU at $3,950 are two very different ways to see a signal. This head-to-head helps you decide which one belongs on your bench.
Choose between a $3.20 non-contact voltage pen and a $6.99 digital multimeter. The pen checks AC voltage fast; the multimeter measures AC/DC voltage, current, and resistance.
Comparing the $225 FNIRSI DPOS350P 4-in-1 digital oscilloscope with the $150 Sencore FS74 TV-RF signal analyzer: one is a modern bench instrument for general electronics, the other a vintage CRT analyzer for off-air TV and FM signals. See which matches your work.
A two-pack of non-contact AC/DC voltage pens is $6.59, while a DC automotive circuit tester with extra probe and clamp is $4.90. Here's how to pick between them.
We compare the $13.87 Digital Clamp Meter with the $54.99 ANENG 683 True RMS touch-screen multimeter to help you choose the right electrical tester for your toolbox.
