Tektronix 5A22N High Precision Arbitrary Function Generator

Tektronix 5A22N High-Precision Signal Workhorse for Demanding Industrial Testing

If you’re debugging motor drives or calibrating vibration sensors in a plant, this isn’t just another signal generator—it’s the tool that keeps your test bench humming. We’ve seen engineers use it for everything from simulating faulty turbine signals to validating safety relays, especially when waveform accuracy can’t slip by even 0.5%. The dual channels mean you never lose signal during critical tests, which honestly saves headaches when dealing with stubborn PLCs.

Truth be told, we keep this one stocked specifically for folks wrestling with legacy GE Fanuc drives or Bently Nevada probe calibrations—like that time a refinery needed to mimic 4-20mA faults on a 3500/44M system. Works like a charm with Triconex 3721 modules too, since the clean square waves won’t trip up those sensitive safety inputs. Honestly, if you’re running Foxboro FBM230/P0926GU loops or Woodward UG-10D controllers, having a stable 10 Vpp source stops those “ghost signal” headaches dead in their tracks.

Personally, I’ve found the real magic in how it handles noise injection tests for Emerson Epro systems—you get dead-on amplitude control even when pumping out 20 MHz random waveforms. No weird harmonics messing up your FFT readings. The dual channels aren’t just for show either; run one as your main signal while the other throws controlled glitches at a Honeywell controller. And because it’s built like industrial gear (not lab fluff), it shrugs off voltage dips that’d make cheaper units hiccup. Just last month, a client used it to validate Yokogawa DCS redundancy switches without a single dropout. Solid as a rock when your plant’s uptime’s on the line.
