This manual provides operating and servicing information for the Hewlett-Packard Model 1331A X-Y Display (figure 1-1). The manual is divided into eight sections, each covering a specific topic or as- p

34、ect of the instrument. All schematics are lQcated at the rear of the manual and can be unfolded and used for reference while reading any part of the manual. 1-3. This section contains a description of Model 1331A. The instrument specifications are listed in table 1-1. Table 1-3 lists and describes t

35、he abbre- viations used everywhere in this manual except in Section VI. The parts list in Section VI is a com- puter printout and uses computer-supplied abbrevia- tions. Special accessories are listed in this section. Standard options available for this instrument are listed and described in Section

36、 VIL 1-4. DESCRIPTION. 1-5. Model 1331A has been designed for general- purpose X-Y storage and system monitoring. It can display digital or analog computer-processed data or real time information. Its high frequency response makes it useful as a read-out device in the following applications: graphic

37、 and alphanumeric displays, nuclear spectrometer, semiconductor curve tracer, swept-frequency measurements, frequency ratios, phase shift measurements, raster displays, and ampli- tude versus time displays. 1-6. Identical X and Y amplifiers provide storage monitor displays with bandwidths up to 1 MH

38、z. Re- fresh memory requirements are minimized by the mesh type storage CRT. 1-7. All controls required to compensate for spot deflection and dot writing speed are located on the front panel. These include FOCUS, INTENSITY, PER- SISTENCE, mode (WRITE, and STORE), POSITION controls, and ERASE. 1-8. M

39、odel 1331A writes and stores shades of gray which adds a third dimension to the display. Spot blanking is obtained with-IV. Maximum brightness is obtained with + 1 V. In-between voltages provide shades of gray. 1-9. Model 1331A is proportioned to permit mount- ing two instruments (any HP 1330/ 1331-

40、series instru- ments) side-by-side in a standard 19-inch rack. Refer to the paragraph on available accessories in this section for a description of a suitable rack adapter. 1-10. CATHODE-RAY TUBE. 1-11. Model 1331A uses a post-accelerator storage CRT with a 10.5 kV accelerating potential and alum- i

41、nized P31 phosphor. The 8 x 10 division internal graticule is located on the same plane as the display to eliminate parallax errors. The mesh type storage used eliminates the need for memory devices to con- stantly refresh the display. Refer to table 1-1 for complete CRT specifications. 1-12. WARRAN

42、TY. 1-13. The instrument (except the CRT) is certified and warranted as stated on the inside front cover of this manual. The CRT is covered by a separate warranty. The CRT warranty and warranty claim form is located at the rear of this manual. Should the CRT fail within the time specified on the CRT

43、 warranty page, complete the warranty claim form and return it with the defective CRT. The procedure for returning a defective CRT is described on the CRT warranty page. The warranty may be void for instru- ments having a mutilated serial number tag. 1-14. AVAILABLE ACCESSORIES. 1-15. Accessories av

44、ailable for use with Model 1331A are listed in table 1-2. Hewlett-Packard also has a wide range of test equipment and accessories suit- able for use with HP instruments and instruments of other manufacturers.
