Set the oscilloscope as follows: Harmonic Distortion Verification The log indicator should light. Using the digital voltmeter to monitor the dc power supply output, set the dc voltage as near 335a 5.

Change A function to square wave. The total quantity of a part is given the first time the part number appears.

Otherwise, both kits are available separately by their -hp- part numbers. The numeric value for the phase is stored, but the phase of the output is not changed when the register is recalled.

Option High Stability Frequency Reference. High Voltage Function Test. The status information byte 8 bits sent by the device will tell whether that device needed service and why. Audio analyzer indication will be dB. Zero volts or dc offset voltage, see Paragraph It is imperative that the fan filter be inspected frequently and cleaned or replaced as necessary to permit the free flow of air through the instrument. For ease of recording data at various times, copies of the blank Performance Test Record may be made without written permission from Hewlett-Packard.

The error decreases as sweep lime is increased. The sweep will stop while any other parameter is being changed, then wili restart. See Table for List of Manufacturers. Low-noise or noiseless, clean ground earth terminal. If the calculator is equipped with a String Variable ROM, the interrogate program may be changed to the following. Change A to pos ramp.

The square wave display should Ire 5 divisions peak-to-peak.

Adjust the electronic counter to measure time in- d. This output is identical to the output at the front panel sync connector. Placing the A in Manuall.

This key must be pressed to select any of the key functions labeled in blue. Change A amplitude to.

Test Equipment for Troubleshooting. Test Frequency Function Minimum Maximum m Minimum times are as follows: Digital voltmeter reading should be – V seevice An instrument manufactured after the printing of this manual may differ in some respect from the information in this manual. With oscilloscope horizontal controls set to main sweep, adjust the intensified portion of the trace to the reset positive going portion of the ramp. Add – 6 dB to this number and enter on the performance test card.

In either single or continuous log sweep mode, the stop frequency must be higher than the start frequency, and sweep is up only.

Connect a dc digital voltmeter to A rear panel X Drive output. Remove the ohm feedthru termination and connect the A output directly to the digital voltmeter input. High Voltage Output Option Approved for public release; distribution is unlimited.

Indicates dangerous voltage terminals fed from the interior by voltage exceeding volts must be so marked. In order to use the Oven Option To print the manual completely, please, download it. Verify that all three readings are between. TB Test instrument parameters Amplitude accuracy with offset attenuation range 1 into 50 load Attenuator xervice these errors are additive with the amplitude accuracy errors Amplitude output Amplitude option high voltage output Dc offset Dc offset option Dc plus ac Not verified below 50 Hz.

Under certain conditions, dangerous voltages may exist even with the power cable removed. The controller then places the bus in the command mode to terminate the message with a Serial Poll Disable command.

Change A function to negative slope ramp. Modulation frequency may be 0 to 50 kHz. Power consumption is VA maximum. The front feet contain foldaway tilt stands for convenience in bench operation.
