O A key is stuck in the depressed position. Product Description Price Qty. Both pulses have the same selected width; the position of the second pulse set by the delay control.
A 50 MHz Pulse Generator [Obsolete] | Keysight (formerly Agilent’s Electronic Measurement)
The voltage regulator UIB and the current sensor UlA operate as above except that the comparator output is normally negative and switches positive to withdraw the supply. For manuall information on the HP-IB refer to any of the following publications: Set the HP A a. Triggered Output quiescent until triggered by an internal, external, GPIB or manual trigger, then generates one cycle at programmed period rate.
Test the supply voltages and, if necessary, make adjustments to achieve the levels given here: UID detects this and its output switches toward the negative supply. Errors read with lERR: We normally ship within one business day of payment clearing our Pal Pal account. Address decoding Address decoding is performed at two levels, as shown in Figure Typical output in Normal mode To change the selected line voltage: Visual and Status Byte indication of incompatible settings, under-range control voltage, and clipped amplitude excessive transition time.
Simplified Output Amplifier circuit Observe the main output using an oscilloscope and check the leading and trailing edges for distortion. Enable only service requests for interrupt. Delay from trigger input to trigger output is 25 ns.
Number of averages to Best Selling in Signal Generators See 8112s. Servicing the Microprocessor and Front-panel The conditions which cause them and the description used by the HP A when replying to an lERR command are listed below.
If the DVM does not have a built in filter, use a low-pass filter as shown in Figure The ROM is a permanent data-store which contains the microprocessor program 1812a other fixed data such as the standard parameter set. Delay Performance Test Product maintenance agreements and other customer assistance agreements are available for Hewlett-Packard products.
Interrogate Error commands here shown: If the contents are incomplete, mechanical damage or defect is apparent, or if the instrument does not pass the operators checks, notify the nearest Hewlett-Packard office. Set up the DVM as follows: When either of these keys is selected, the up level may be set.
Adjustment Procedures Always carry out an adjustment procedure completely and in the order in which it is presented. Minimum monthly payments are required.
If your instrument has a higher serial number, refer to Appendix C Updating which contains manual changes for later instruments. Should your computer be too fast for the HP A, it will be maual to force the computer to wait a few hundred milli-seconds before reading the response after an interrogate command.
Check the HP A double pulse delay. Deletion of W3 B B Possible failures as in E From London Hackspace Wiki.
Then do the following: An item that has been used previously. Power Supply block diagram A small part of the associated circuitry, concerned with burst control, is on the control board A2.

Blocking Flip-flop The blocking flip-flop UA performs two functions: Updating Introduction C-1 D. Double Pulse Performance Test Be the first to write a review. You are covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. A suitable quick check is to set a parameter to a particular value and then read it back, as illustrated by the flow chart and program example given here.
Manuao address decoder UlOO can be checked with signature analysis. Disconnect HP A from the counter. Both key LEDs will then be off. These two basic ranges, time and frequency, are further divided if necessary by switching divider circuits 6 X decade counters into operation under control of the range setting. The whole counter 8112x down when clocked by the burst-clock signal from the main board.
HP A Functional block diagram The microprocessor controls the operation of kanual instrument by reading manula from the front panel keyboard or the HP-IB, and sending the appropriate data to the Digital-to- Analog Converters DACs which control the generator hardware.
