What it is
How it works
The Type 454/R454 is a general-purpose, environmentalized, high-performance, portable, wide-band oscilloscope featuring DC to 150 MHz bandwidth combined with a dual-channel vertical amplifier and delaying sweep. The Type 454/R454 has a 5 ns sweep rate with X10 magnifier, stable triggering to bandwidth limits, and calibrated X-Y capabilities. A 5 MHz bandwidth limiter switch provides for viewing low-frequency, low-level signals with reduced noise and RF interference. The Tektronix 454 has a 140 ns delay line in the signal path after the input channel switching and before the main vertical amplifier. The Tektronix 454 uses a CRT with distributed vertical deflection plates. The Tektronix 454 uses a T4540 CRT with P31 phosphor as standard and P11 as an option.[2][4][3]
Where it fits in the process flow
General reference — not yet source-verifiedAn oscilloscope is a support instrument rather than a production process tool. An oscilloscope is used around development benches, maintenance stations, and instrument racks to observe electrical behavior in supplies, control electronics, detectors, drivers, and communications links. An oscilloscope generally sits alongside the equipment under test rather than directly in the material processing path.
Applications
The Tektronix 454 is intended for general-purpose signal observation and measurement. The Tektronix 454 provides dual-channel operation, delaying sweep, calibrated X-Y capabilities, and stable triggering to bandwidth limits. The Tektronix 454 includes two probe power connectors that provide operating voltages for P6045 FET probes.[4]
- field work applications
Why won't it start?
Documented failure modes, common issues, and field considerations.
- The 454 and related models have several resistors with underrated wattage.
- A nonfunctional delay sweep in one 454 example was caused by R1257 being 10% high in value.
