A 5V pulse on this pin at a Triangle and ramp waveshapes are also available with. The width of the positive pulse should decrease to zero, then reset and repeat at a 1 Hz rate TTL levels.

Amplitude Flatness Adjustment 5- 3. Signature Analysis does have its limitations. Exceptionally linear triangles and ramp signals are produced with synthesized accuracy and stability for applications such as VCO testing or process control.

The oven output frequency is 10 MHz. Connect an electronic counter to the signal output, using ohm input termination. The Sync signal then is passed through buffer circuits to the front panel. Equipment Required If the square, triangle, and ramp functions are inoperative, or if the DC Offset no ac func- tion is one-half the programmed level, the problem may be in Offset Control circuits U38B, Q, U41B,orQ For this frequency, the fractional-N counter is trying to correct the phase detector error for the IHz offset.

Primitive Power On Tests The dc-to MHz frequency range sine makes the B ideal for high-performance video system testing. The concept of Signature Analysis is based on the fact that at a particular point in a circuit, the data pulses are predictable under specifically programmed conditions.

Document Outline

To generate a triangle wave, the sine wave input is first put through the squaring circuit, then divided by 20 -j and Amplitude Modulation does not respond properly. This is the VCO control voltage. The Control Circuits include the following: This sine wave is applied manua the function circuits where both the output function and signal level are determined, again by digital control. Connect the Main Signal output connector to the oscilloscope vertical input. This biases Q into conduction.

The power stage should still operate if they are removed.

An easy way to accomplish this is to use a dc power supply with a IkO resistor in series with its output. Please note that Hewlett- Packard’s former test and measurement, semiconductor products and chemical analysis businesses are now part of Agilent Technologies. This disables the Shift Register and the Pulse Manuzl circuits.

Amplitude Flatness 5- K4, swit K3 control the output signals attenuation. Set the oscilloscope as follows: These adjustments should be used following repairs or if performance tests indicate a deficiency. The signal level from the output amplifier can be tested in the level comparator to determine if a level correction is needed, thus providing an automatic amplitude calibration.

If the sine function is operating properly, but none of the other functions is correct, the trouble is probably in the QlOl, Q circuits or U31 inverters. Readjust V ADJ if necessary.

Square Wave Gain-Offset Indicates dangerous voltage terminals fed from the interior by voltage exceeding volts must be so marked. Press the Local key to exit Special Test Mode Simplified Illustration of Triangle Generation.

Amplitude Flatness Adjustment 10Vp-p Pad. The value of the current to the integrator depends upon the X Drive analog voltage and the resistance in the integrator input circuit. Figure is a simplified illustration of this.

Function Sine Amplitude 0. This signal goes low at the start of a linear or log single sweep, high at the end of the sweep, and remains high until the mamual of another sweep. Two numbers are displayed for a moment. Repeat Step d, adjusting as necessary.

This section of the instrument provides the proper current to the operational output amplifier for each function. If this signal is not correct, the trouble is ahead of the SINE test point.

An over-voltage protection circuit in the unregulated -i-5V supply prevents the voltage from becoming high enough to damage the supply circuits.
