GENERAL DESCRIPTION The 306-5

34、9992A is a special instrument used to increase the accuracy of precision time interval measurements. When employed to determine the sys- tematic errors of a particular measurement set-up, the calibrator can provide for absolute accuracy on the order of +/- 100 ps when making time interval measuremen

35、ts with the Hewlett-Packard 5370A/B Time Interval Counter. The calibrator can also be used to improve the accuracy of the HP 53630 Time Interval Probes when used in conjunction with the HP 5370A/B counter. The instrument itself is a linear, passive device which takes a stable input pulse and produce

36、s two output pulses that are effectively in phase or 180 degrees out of phase. This provides two identical and coherent signals to the input of a measurement instrument such,as a counter. Any time difference measured by the counter in a calibration set-up is a measure of the errors as- sociated with

37、 the measurement channels electrical path lengths and the trig- ger level timing error of the counter. The resuitant computed calibration constant is then subtracted from the measurements that follow, thereby removing the effect of systematic enon from the measurement results. Page 1-1 www. HP J06-5

INTRODUCTION INSTALLATION This section presents the information needed to prepare the HP J06-59992A Time Interval Calibrator for use. Information to prepare for remote opera- tion using HP-IB (Hewlett

44、-Packard Interface Bus, HPs mplementation of IEEE Std. 4 8 8- 19 7 8) is also included. Ma 1 2-2. PREPARATION FOR USE 2-3. Power Requirements The J06- 59992A Time Interval Calibrator operates from either 1 1 S or 2 30 volts, 48 to 66 Hz Before applying power, the voltage selector switch mounted on t

45、he rear panel of the J06-59992A must be set to the correct position (1 15 or 230) using a small screwdriver, and the correct fuse must be installed. This instrument uses a .2A 2 50V time-delay (TD) fuse for 1 1 5 volt operation or a .lA 2 50V time-delay (TD) fuse for 230 volt operation. Refer to Tab

46、le 5-3 in Replaceable Parts for the HP Part Numbers of these fuses. BEFORE PLUGGING THIS INSTRUMENT INTO THE AC POWER LINES, be sure the correct voltage and fuse have been selected. This is a Safety Class I product (i.e., provided with a protective earth terminal). An uninterruptible safety earth gr

47、ound must be provided from the Mains power source to the product input wiring terminals, power cord, or supplied power cord set. When- ever it is likely that the protection has been impaired, the in- strument must be made inoperative and be secured against any unintended operation. If this instrument is to be energized via an external autotransformer for voltage reduction, make sure that the common terminal is connected to the earthed pole of the power source.
