HP A Pulse Generator Operating & SERVICE Manual | eBay
Switch filter OFF or remove external filter. The parameter window will be automatically illuminated. With a logic high on the input, Q is switched on and in turn switches Q off, to produce a low 0 V output.
See other items More Free Running Signature Analysis To carry out signature analysis the microprocessor must be set to a free-running routine in which it increments through all addresses continuously. Servicing the Microprocessor and Front-panel The right hand vernier key is used to alter the value of X, to determine which file the parameter set will be stored as.
The offset signal is applied to the non-inverting input at the junction of CR, CR 812a ensure a constant reference point.
Trending Price New. Then press the green SETl key. The oscilloscope response is very slow for measurements with PER in the ms range.

Both pulses have the same selected width; the position of the second pulse set by the delay control. Display Board Control Board Figure If the instrument battery has failed, the Standard Parameter Set is selected. The output from U19 therefore represents the state of the key joining the manul signal path addressed by A3-A5 and the horizontal signal path addressed by A0-A2.
The approximate value of current drawn by the input current pins is shown below. Press the [lcl] key again to set the new address. Have one to sell? Address Decoders Refer to Figure Delay Performance Test Flex the power cord during the measurement to check for any intermittent discontinuity.
Range Upper Limit ns ms Enables a data bus driver U36, which allows the remote programmer to read the address set on the HP-IB address switch. The limit 1 key LED is lit when this mode is active. Warning JH Do not change a component while power is connected to the instrument.
Each active input edge triggers a burst of pulses [BUR] 1 to pulses. The item you’ve selected was not added to your cart. The adjustments described in this chapter are performed with the instrument switched on and its protective covers removed. The RAM is used to store the current parameter set and temporary data needed by the microprocessor.
Any international shipping and import charges are paid in part to Pitney Bowes Inc. The new cosine transitions, also variable from 6. Duty Cycle Performance Test Procedure 1.
Figure and Figure show the front and rear panel respectively.

At this moment there is neither a syntax error or SRQ active. Amplitude Gain Control truth table Typical signals in Trigger mode 1. Display shows max value available in selected range. Inspect the interior of the instrument for any signs of abnormal overheating or arcing, such as: Note that to prove that the instrument is within specification, only the Performance Tests have to be carried out.
In this configuration the BURST ON signal is active lowonly when all the the counter inputs are low signifying the burst is complete. ROM layout B B Fuse The fuseholder accepts standard fuses to provide instrument protection in case of current overload.
EOI cannot easily be turned off. Output controls Range Decoder Truth Table See full item description. Verify that each external input pulse triggers an output pulse of the same width, as shown here. Back to home page. General instructions for repacking are as follows; 1.
The HP A status byte can be read manuql a serial poll.
