Select the delta V menu and turn the voltage markers On.
A brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Logic signals K1 – K4 control relays K – K to provide three levels of attenuation according to the range of output voltage required.
Input The signal from the shaper IC current-mirror is applied to the inverting input where it is amplified by Q and Q common base amplifiers.
The HP A needs time to interpret and implement the commands which it receives. The possible error codes are: Use a 50 feedthrough termination if you cannot select 50 fi input impedance on the counter. The vernier keys are inoperative and the Range key is used to change range. Decade Accuracy The first four digits only change when there is a significant modification to the instrument, the last five digits are assigned sequentially to instruments.

These decouple the voltage gain stage from the low output-impedance. Vary the power supply between approx 1 volt and 10 volts and verify that for the following HP A settings, the range of times displayed agrees with those specified. Select a valid country. Possible faults in leading edge slope control circuit U12, U14 or U Test the supply voltages and, if necessary, make adjustments to achieve the levels given here: The counter is then clocked by output pulses from the period generator on the main board Al.
The HP A status byte can be read using a serial poll. No ratings or reviews yet. Period Generator Input pin 7 If the plug on the cable does not fit the power outlet, or the cable mnual to be attached to a terminal block, cut the cable at the plug end and re- wire it. Allocate memory for max- imum reply length Request current settings of instrument Read reply into allocated memory Print the reply. An adequate wait period here ms will give the HP A enough time to process the command and update the status byte.
,anual the Timing and Low Pass Filter To check operation of the Ext. Selection Pressing a parameter key selects the parameter indicated by the illuminated mnemonic above the key.
This item doesn’t belong on this page. If bit 7 is set decimal value of the STB is bigger than then the buffer is not yet empty.
Transition Controis The transition mode keys enable the operator to select the type of pulse transition and to vary transition time. Each vernier key increments or decrements the corresponding digit in the digital display.
Connect the HP A and oscilloscope as shown in Figure The error 8112a from the timing IC indicates that a trigger signal has been received before the completion of the previously triggered event. SuperSaiyan Yes, this is 8112s of the reasons.
Each of the bits 0 thru 5 summarizes a speciflc type of error. Remove the case by sliding it backwards. Main Board A1 – Schematic 6 Period Generator ramp signal pin 20 Press the disable key to turn off output disable mode and enable the output LED extinguished. Each group of controls is explained in subsequent sections of this chapter under the following headings: Standard Control Board A2 – Schematic 3. The delay time is dependant on the analog inputs, internal range data, and triggering mode.
