Specialized - Cathode Ray ·CathodeRay
Philips DH-series cathode-ray instrument tube designed for oscillographic and measurement display, with manufacturer-defined high-performance focusing, deflection, screen, and accelerating characteristics for type DH1310.
Flat-face post-deflection-acceleration high-sensitivity cathode-ray oscilloscope tube. The source provides CRT heater, focusing/deflection, capacitance, scan/sensitivity and operating data where published.
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
1 physical section, each with unique specifications.
Section 1
No fixed ratings are recorded for this section.
CRT-specific optical, focusing, deflection, accelerating-voltage, scan, and capacitance data are retained in TUBE_SECTION_PARAMETER because the locked promoted fields primarily target conventional electrode sections.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
