Main Board A1 – Schematic 7 Safety Check The following safety checks must be carried out after any servicing is completed; 1. When operating the HP A, choose a location that provides at least 75 mm 3 inches of clearance at the rear, and at least 25 mm 1 inch of clearance at each side. Self-test and fault diagnosis are performed each time the instrument is switched on. Servicing the Control Board Email to friends Share on Facebook – opens in a new window or tab Share on Twitter – opens in manuao new window or tab Share on Pinterest – opens in a new window or tab Add to watch list.
The time taken for the HP A to mmanual and implement a programming message can be divided into three parts: These tests check pulse generation using the level check circuits.
Width Generator Input This is an alternative to using the WAIT statement with a fixed delay. Replace the transistor s.
Check the ramp signal at pin 20 of U against Figure Adjust A1R until the measured voltage is 5. Use the vernier keys to change the address. Note More than one error condition can occur at one time.
Nov 14, 1. The decoder output lines determine which timing, mode or range circuit latches data from the data bus LDO to LD7 as shown in Table Test setups, up to 99 locations, can be stored and recalled. Active slope moves from Range 3 to Range 4 Y2 Inactive slope Change Value Reason XI xlOO in shared overlap X2 xlO not in overlap X3 no change in overlap with higher range When this key is used to move a currently active slope up or down a range, the non-active slope will be automatically pulled into the Same Decade as the active slope setting.
This item has been inspected and it is in good condition. Connect the equipment as shown in the setup figure above.
This is verified by using the power cord which is supplied manuak the instrument.
Servicing the Shaper and Output Amplifier Refer to Chapter Duty Cycle Performance Test When the High Level Control HILC is selected, the control input signal is routed through the switch U and low pass filter Ua with associated componentsto the output stages. If no settings have been stored, the instrument will revert to standard settings whichever file number is selected for recall.
No other warranty is expressed or implied. If a fault is detected an error code is displayed, otherwise the instrument is ready for operation.

When linear or gaussian mode is selected, the slope generator relies on four current sources and a switched range capacitor network to produce variable transition time leading and trailing edges, depending on the LEE and TRE DACs in the control section See Chapter Set the HP A Period to the following values and read the actual output from the counter.
Adjust A1R for 5. Period Generator output signals For fixed transitions, the single ended EECL input is used to provide fast, fixed mode output pulses having a fixed transition of 4.
The counter is then clocked by output pulses from the period generator on the main board Al.
