The Tektronix Type 317 is a portable, all-tube CRT oscilloscope designed for general-purpose waveform display and analysis in high ambient light environments. Introduced circa 1959, the instrument employs a 3-inch PDA (Post-Deflection Acceleration) CRT with 9 kV acceleration voltage to deliver a bright, high-contrast display suitable for field diagnostics and bench testing. The Type 317 provides DC to 5 MHz bandwidth with vertical deflection sensitivity of 9 V/div and horizontal deflection sensitivity of 26 V/div. Triggering modes include AUTO, AC, and DC to accommodate a variety of signal conditions. The compact, portable design measures 20 × 18 × 12 inches and weighs approximately 20 lbs, incorporating a rear-mounted cooling fan. Power consumption reaches 275 watts at 198–235 V AC operation (wired for 220 V).

– Compatibility & Integration
A rackmount variant, the RM17, is available for stationary installations. The Type 317 shares design heritage with the Type 316 but incorporates higher CRT acceleration voltage for enhanced display brightness. Compatible CRT assemblies include Tektronix part numbers 154-0196-00, 154-0216-00, 154-0217-00, 154-0218-00, and 154-0346-00. Complete instruction and service manuals with schematics and parts lists are available.
