Audio analyzer indication will be dB. To rack mount with handles, the combination kit of item b Option must be used see Figure The oscilloscope should display one triangle wave with no visible irregularities in either slope. Control Circuits Service Group C. Disconnect the thermal converter from the A output. After interrogation, the error code is set to zero until jp next error occurs.

Mnaual instrument should be stored in a clean, dry environment.

Oscilloscope -hp- Model A The 6 dB is a correction factor compensating for the folding action of the mixer. Sine 40 V 4 mV Programming Amplitude Units Conversion. The tilt stand raises the front of the instrument for easier viewing of the control panel. Several devices may be assigned to the same bit and level, causing their response bits to be logically ORed or ANDed.

Sine Amplitude Control and Amplitude Set the input to dc coupled. Set A dc offset to V.

HP A User Manual | 23 pages | Also for: B

Yp program used for this test is written specifically for the -hp- Model A Calculator but may be adapted to other controllers. Without changing the reference level, set the A frequency and the spectrum analyzer center frequency to the frequencies listed below.


Frequency automatically changes to 10kHz. Test Frequency Function Minimum Maximum m Resolution of a dc offset entry with ac function is determined yp the resolution of the ac amplitude.

Enter 20 MHz in the A. Instruments in this range do not have A3R or A3C Repeat tests i through z. Change oscilloscope delay to and read negative peak. Change oscilloscope horizontal control to. The standard Model A provides selectable front or rear panel ohm signal outputs.

Direct current power line. The kit is shipped with the instrument if Option is also ordered. If your oscilloscope doesnot have a ohm input, use a ohm load -hp- Mode!

A TTL compatible output maanual present during a sweep operation see Paragraph Using the Modify keys, adjust the phase until the counter reads approximately nanoseconds.

The output automatically switches to the AUX output when frequencies of 21 Page 3 Test instrument parameters Harmonic distortion relative to fundamental at full output Amplitude modulation Square wave Ramp retrace Frequency Sine wave Square wave Triangle Positive slope ramp Negative slope ramp Phase offset Amplitude Amplitude accuracy with no attenuation attenuator range 1 into 50 load no dc offset Flatness with no attenuation The test equipment required for the Performance Tests is listed in Table Replace the screw in the oven assembly and repeat Step e.

Bits 3 through mznual in the status byte can be masked 3235a that the corresponding conditions will not cause a service request. For protection against electrical shock in case of a fault.


The power jack and mating plug of the power cable meet International Electrotechnical Commission IEC safety standards.

Set the output manjal to 10 Vp-p. Manuao warranty statement is located in the front of this manual. TP9 and TP10 Waveforms. For instruments with serial numbers A to A, refer to Service Note A-9 if necessary for a modification procedure to prevent oscillator failures. One cycle of the square wave should fill the screen of the oscilloscope, and the sample time for the voltmeter should be seen as the intensified spot hl the delayed sweep. Others are general messages to all devices.

Connect the oscillator output between the center contact of A3J23 and ground. Verify that all three readings are between. Press the Negative Ramp function on the A. The numbered delta in the text or on a manuap corresponds to the numbered delta shown in the heading that precedes the backdating information for that particular service group.

This manual also for: These instruments do not have C Refer to Figure for the connector configuration and -hp- part numbers of the available power cables. Protect the control panel with cardboard, d.
