The front feet contain foldaway tilt stands for convenience in bench operation.

Using the digital voltmeter to monitor the dc power supply output, set the dc voltage as near – 5. Polling – Polling is a means by which a controller can identify a device that needs interaction with it. The newer connectors are incompatible with the older cables as arc the newer srevice incompatible with the older connectors. Change the power supply output to the following voltages and repeat Steps j through m for each. Instruments in this range do not have A3R or A3C A6 – Past to Present.

Included are initial inspection procedures, ,anual and grounding requirements, sservice voltage selection, environmental requirements, installation instructions, HP—IB connection procedure, and instructions for repackaging for shipment. The power cable must either be plugged into an approved three-contact electrical outlet or used with a three-contact to two-contact adapter with the grounding wire green firmly connected to an electrical ground safety ground at the power outlet.


Set A frequency to 2 kHz and amplitude to 40 Vpp. Change the A function to triangle. Oscilloscope display should show one servixe wave per division, 5 divisions peak-to-peak vertical.

The output voltage should be 3. Does not cause SRQ. Option is a temperature stabilized 10 MHz oscillator which provides improved frequency stability see specifications in Table Press A High Voltage Output key lower right corner of front panel.

Equipment required to maintain the Model A is listed in Table The warranty statement is located in the front of this manual.

Service Model A Table Simplified Illustration serviice Ramp A and Below. In this case, a yellow Manual Changes supplement included with the manual explains how to adapt the manual to your instrument, 1 Power is applied to some circuits at any time the instrument is connected to the ac power source.

It should be from Connect DC digital voltmeter with microvolt resolution -hp- A to thermal converter output. Connect the equipment as shown in Servife The instrument can be rack mounted with or without a handle setvice by use of the following items: Items marked by a dagger f in the reference designator column are available only for repair and service of Hewlett-Packard instruments.

Connect the A signal output through a ohm feedthru termination to a dc digital voltmeter input.

After receiving an interrogation, the A will send back the following the next time it is addressed to talk: Sine Amplitude Control and Amplitude A2 manuaal Page 8-C, Figure This checks the output with no attenuation. This number can be used hl order 4×6 inch transparencies of the Operating and Service Manual, Each Microfiche contains up to 96 photo-duplicates of the manual pages.


The following front pane! See Service Note A-5A for a modification procedure to improve square mnual phase control in these instruments. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.

The controller requests device status from one device at a time. These bandwidth modification keys do not operate in log sweep mode. Set the spectrum analyzer center frequency to Electronic counter should indicate 10 Change the spectrum analyzer center frequency to If your oscilloscope does not have a ohm input, use a ohm load -hp- Model C ohm feedthru termination at the input.

Control Circuits Service Group C. Include instrument model and serial numbers.

Got it, continue to print. The characteristics of the two modes are: Wait statement allows time for sweep to start before reading status. In instruments with High Voltage Output Optionthis key switches from norma to high voltage output, and the annunciator indicates when the high voltage output is on.

Under certain conditions, dangerous voltages may exist even with the power cable removed. The programmable selection functions are:
