The MX-

14、2962/USM-l05A is an auxiliary unit for plug-in installa- tion in the froat-panel receptacle of the oscilloscopes listed below. The purpose of the MX-2962/USM-l05A is to delay the start of the oscilloscope sweep a selected time interval after application of a triggering signal. No circuit adjust- men

15、ts are required and no loss in specified calibration accuracy occurs to the MX-2962/USM-l05A when it is used interchangeably in any of these oscilloscopes: AN/USM-lOSA supplied on Contracts NObsr 75278 and NObsr 81535; see NAVSHIPS 93658. AN/USM- 139 AN/USM-140 AN/USM-141 NAVSHIPS 94309 consists of

The MX-2962/USM-l05A and 166Dare alike in performance specifications and electrical

The Model 166D Delay Generator is a plug-in unit which provides the ( $ 3 Models 160B and 170A Oscillo- scopes with delayed sweep capability. Two modes of delay are provided, one in which the oscilloscope sweep starts at the end of the de

19、lay period, and one in which the oscilloscope sweep is armed at the end of the delay period but does not start until triggered independently. The Model 166D itself generates a linear sweep(the delaying sweep). The delaying sweep can be used to measure delay, indicate the starting point of the de- la

20、yed sweep of the oscilloscope, and provide mixed sweeps in which the delaying sweep drives the trace for approximately the delay period and the oscillo- scope sweep drives the trace for the duration of the display. The Model 166D is designed with specification MIL-E-16400C as a guide. The instrument

21、 meets the environmental specifications of oscilloscope models 1608 and 170A when installed in an oscilloscope. Model H02 166D Delay Generator is identical to Model 166D in specifications, operation, and applica- tion. However. the Model H02 166D uses electron tube and semiconductor types which are

22、MIL approved. Where these types differ from the commercial types used in the Model 166D, both types are listed and identified with the correct model in the table of re- placeable parts. All other references to the Model 166D apply equally well to the Model H02 166D. Tables 1-1 through 1-4 list refer

23、ence data for the Model 166D. 1-2. ELECTRON TUBE TYPES 6922/6DJ8. Electron tube types 6922 and 6DJ8 are equivalent, and either type can be used where called for in the instrument. However, the two types draw different heater current. Since the heater circuit is balanced to ground, use only one tvpe

24、or the other. 1-3. CHANGES. The Model 166D carries a five-digit serial number with a three-digit prefix: 000-00000. The three digit prefix appears on the title page of this manual to indicate to which instruments this manual applies directly. A supplement or change sheet may be in- cluded with this

25、manual to indicate the manual changes required to make the manual apply directly to instru- ments which carry a different serial prefix. Table 1-1.

UNPACKING A N D INSPECTION. Unpack and inspect the Model 166

33、D as soon as pos- sible after receipt. Save the packing materials until the inspection is complete, for these materials may be needed for reshipment in the event of shipping damage. Inspect the Model 166D for signs of physical damage such as an abraded panel, broken knobs, etc. If pos- sible, instal

34、l the Model 166D in either an Model 160B or 170A Oscilloscope and check the unit electri- cally. Refer toparagraph 6-3. If there is any damage, file a claim with the carrier. Refer to the warranty page at the rear of this manual. 2-2. INSTALLATION The Model 166D is a plug-in unit for Models 160B and

35、 170A Oscilloscopes. To i,nstall the Model 166D, slide it into the front-panel openingof the oscil- loscope directly below the crt. Lock the unit in place to insure good electrical and mechanical connection. All necessary operating power for the Model 166D is supplied by the oscilloscope. To check t

36、he Model 166D performance, refer to paragraph 6-3. Note To realize the specified accuracy of the Model 166D. operate it in an oscilloscope in which the +110 volt and -100 volt power supply voltages are within 0.4% of their nominal values. 2-3. REPACKAGlf SECTION 111 G FOR SHIPMENT. The following is

37、a general guide for repackaging an instrument for shipment. If you have any questions, contact your authorized Hewlett-Packard sales office. (1) If possible, use the original container designed for the instrument, (2) Wrap the instrument in heavy paper or plastic before placing it in the shipping co

38、ntainer. (3) Use plenty of packing material around all sides of the instrument and protect panel faces with card- board strips. (4) Use a Heavy cardboard carton or wooden box to house the instrument and use heavy tape or metal bands to seal the container. (5) Mark the packing box with “Fragile”, “De

39、licate Instrument”, etc. as appropriate. Note If the instrument is to be shipped toHewlett- Packard for service or repair, attach to the instrument a tag identifying the owner and indicating the service or repair tb be accom- plished. In any correspondence. identify the instrument by model number, s

40、erial number, and serial number prefix. ! : I I I I OPERATORS SECTION 3-1. FUNCTIONAL OPERATION. The Model 166D is a plug-in unit for use with 160B and 170A Oscilloscopes. The unit gknerates a linear delaying sweep which permits delay of the main sweep of the oscilloscope for a selected time interva

41、l after an input trigger. At the end of the delay period, the Model 166D produces a trigger pulse which either triggers or arms the main sweep, depending upon the delay function selected. The trigger is also avail- able at the front panel for external use. The sweep or combination of sweeps to appea

42、r on the crt is determined by one of four sweep selections: 1) MAIN SWEEP, in which the main sweep operates normally and drives the trace across the crt with no delay: 2) DELAYING SWEEP, in which the delaying sweep drives the trace across the crt and the delayed main sweep appears as an intensified

43、segment of thedelaying 01227-1 sweep: 3) MAIN SWEEP DELAYED, in which the de- layed main sweep drives the trace across the crt; and 4) MIXED SWEEP, in which the delaying sweep drives the trace across the crt for approximately the delay period, and the main sweep completes the trace. 3-2. PREPARATION

44、 FOR USE. The Model 166D can be operated in any Mdel 160B or 170A Oscilloscope. However, for rated accuracy, the + 110 volt and -100 volt power supply voltages in the oscilloscope must be within 0.4% of their nominal values. Check and if necessary adjust these voltages. To permit best use of mixed-s

45、weep operation, the trace produced by the main sweep must be a given a8nount longer than the trace produced by the delaying sweep. Check the relative sweep lengths as follows: 2- 1 3- 1 Section 111 Paragraphs 3-3 to 3-4 (1) On Model 166D, set SWEEP SELECTOR to MIXED SWEEP, DELAY LENGTH to about 5 CM

46、, DELAY FUNCTION to TRIGGER MAIN SWEEP, and SWEEP MODE to FREE RUN. Model 166D, MX-2962/USM-l05A (2) On oscilloscope, set SWEEP MODE to PRESET. (3) Set DELAYING SWEEP on Model 166D to 20, 10, 5, 2, and 1 MlLLISECOND and set SWEEP TIME on oscilloscope so main sweep is in each case 100 times faster th

47、an delaying sweep. (4) Observe trace on crt for each combination of sweeps. Left half of trace should be brighter than right half. An increase of trace intensity at.right end of the trace indicates incorrect relative sweep lengths. Refer ,to section IV of this manual and to oscilloscope manual for sweep length adjustments. 3 -3.
