However, consider it a warning that the instrument may not meet all of its specifications or may have a marginal failure. Calibrates all functions, then inhibits further calibration. From the mixer, a MHz signal is supplied to the function circuits, the output am- plifier, the attenuator, and on to the instrument output. If the preset number in the 3rd Digit Counter was greater than one, the LSD Counter continues to count, supplying an enable pulse to the 3rd Digit Counter each time it reaches zero.
This lists fust the board number followed by the schematic number. Writes data through the serial isolation path, then reads it back.
The voltages shown on the schematic are measured with the instrument in the Preset state. Except Ul, all other devices on the Data Bus are disabled.
The Q output from this counter goes to the fractional N control IC and is used to clock data in and out of the four shift registers within the 1C. To minimize subsequent drift, the instrument should be connected to ac power for at least 12 hours before attempting this adjustment. These values are obtained in one of three ways: The voltage at TPll should be -i-5V. The revision of this manual applies directly to all instruments.
If the pulse width in Step c or d increases and decreases, the pulse reset circuits are not mamual, and the output signal should be a triangle, at a 0. The effect of this adjustment can be observed only after another single sweep.
Function switching is accomplished by the enable signals shown in the block diagram, Figure Ramps are reset 3325n the digital Phase Detector at frequencies below Hz, and by the analog output Level Comparator at frequencies of Hz and higher. Consequently, in the square wave function, the sine wave must be twice the output frequency, and the maximum output frequency is 10 MHz. Figure Figure Any error found during these tests are indicated by flashing LEDs on the Control assembly.
In this case, the calibration values are left imtouched. Miscellaneous parts are listed in Table following their respective assemblies. Amplitude Modulation does not respond properly.

The phase detector then uses the phase difference between its two inputs to change the VCO frequency to 50 MHz. If input pulses are present, A3U10 may be defective. Front Panel Special Functions Figure is a simplified illustration of this. Direct current power line.
Press Local several times to quit. In response to programming inputs from the keyboard or the interface circuits, the control circuits set the frequency, signal level, and output attenuation. Indicates dangerous voltage terminals fed from the interior by voltage exceeding volts must be so marked.
The fast rise times normally require precise terminations, but the RC filter at the output slows the edges just enough to prevent undesirable reflections e. The result is a square wave whose frequency is 1 MHz plus the programmed output frequency. In normal operation, the sigiial at the collector of Q should be essentially the same as the signal at the junction of R and R Service information is organized into service groups, which include schematic diagrams, block diagrams and troubleshooting information for specific areas of the instrument.
Placing a load on the output further improves reflection problems, but it decreases the signal amplitude to a level that may be just below valid TTL levels. It calls attention to procedure, practice, condition or the like, which is essential to highlight. With Sine function off: Location of Adjustment 6- 1. Because the square wave, triangle, and ramp signals are generated by switching the unipolar amplitude Model Service control current source on and off, the entire signal is above ground.

Location of all adjustments is shown on Figure at the end on this section. The data is now in U, and the register address is in U The Mixer circuits are diagrammed in Figure Press the Local key to exit Special Test Mahual If the output signal has distortion problems on either the top or the bottom portion of the waveform, then troubleshoot the respective half of the power stage, top or bottom.

Range 1 is high for sweep times of 0. Press the 0 key again to verify. Test Equipment Required Let us assume that this is true, and that the -h N number is
