Page 19 Measurement/computation circuit MONITOR The TA220 is a jitter measuring instrument that utilizes signal processing circuits (auto slicer, equalizer, and PLL) for support of the Blu-ray Disk standard (hereinafter, BD) of next-generation high precision optical discs. When BD-standard RF signals are input to the instrument, the PLL circuit regenerates the clock signal enabling measurement of the data to clock (D-to-C) jitter.
Page 20: Measurement Principle
Measurement Principle Example with Pulse Width Measurement A time shorter than the period of the measurement clock is called the fractional time. In general, since the measured signal and the measurement clock are not synchronized, fractional time exists both at the beginning and at the end of measurements. This instrument generates a “fractional pulse”...
Page 21: Measurement Functions (Measurement Items)
Measurement Functions (Measurement Items) Pulse Width Jitter <<For procedures, see section 4.1>> Pulse Width Measurement You can measures the pulse width from the rising edge of the slope* to the next falling edge of the slope (positive side) or from the falling edge of the slope to the next rising edge of the slope (negative side) of the data signal.
Page 22 2.3 Measurement Functions (Measurement Items) D-to-C Jitter <<For procedures, see section 4.1>> Measuring Phase Difference You can measure the phase (time) difference from the rising (or falling) slope of the data signal to the first rising slope of the clock signal. •...
Page 23 2.3 Measurement Functions (Measurement Items) D-to-C Jitter Excluding 2T <For the setup procedure, see section 4.1> This is one of the functions available for measuring D-to-C jitter. D-to-C jitter is measured, excluding the phase difference of data signals having pulse widths of two times the clock signal period (2T) or less.
Page 24: Measurement Conditions
Measurement Conditions Measurement Block The TA220 repeats a three-part process of measurement, data processing, and display. The smallest unit that is measured during the first part of this process is called a measurement block. In the figure below, N is the number of samples (number of data) acquired in a single pass of the process, and the measurement, data processing, and display of these samples is considered to be one block of measurement.
Page 25 RF signal applied to the measurement input terminal. Using the slicer of the TA220, the RF signal is binarized by setting the portion of the signal that is greater than the given slice level* to the positive side and the portion that is less than the slice level to the negative side.
Page 26 2.4 Measurement Conditions Trigger Mode and Slice Level <<For procedures, see section 4.4>> When measuring the pulse width or phase difference of a single pulse, you can select the level of the data signal at which to make the measurement (activate the trigger). Slice level refers to the signal level used to binarize the RF signal.
Page 27 Auto Arming (Internal Arming) The internal signal of the TA220 is the arming source. Arming is the cue used to start the first measurement (the first trigger). External Arming Arming is activated when an external signal (arming source) is applied to the external arming input terminal.
Page 28 2.4 Measurement Conditions Inhibit <<For procedures, see section 4.8>> You can inhibit measurements by applying an external signal to the inhibit signal input terminal. This is possible even while the gate is open or during measurement after arming activation. You can also select which polarity of the signal, positive or negative, is used to inhibit measurements.
Page 29 2.4 Measurement Conditions PLL Hold <<For procedures, see section 4.9>> The PLL hold function maintains the frequency of the clock signal regenerated in the PLL circuit when Inhibit is active. If RF signals whose clock signals cannot be regenerated in the PLL circuit are input to the measurement input terminal when Inhibit is active, once Inhibit is cleared, if a normal RF signal whose clock signal can be regenerated in the PLL circuit is then introduced, the clock signal will be generated normally.

Page 31: Signal Output
Signal Output DC Output of the Jitter Ratio <<For procedures, see section 7.1>> DC Output of the Jitter Ratio The jitter ratio of the selected measurement function can be linearly converted to DC voltage (0 to 5 V) and output from the jitter ratio DC output terminal on the rear panel. You can also change the jitter ratio that corresponds to 0 V and 5 V.

OFF the power switch. From the rear panel, check for and remove any foreign object that may be obstructing the cooling fan. If error message 906 appears when you turn ON the power switch again, it is probably a malfunction. Contact your YOKOGAWA dealer. Handle the Power Cord Correctly Nothing should be placed on top of the power cord.
Page 35 3.1 Handling Precautions General Handling Precautions Do Not Place Objects on Top of the Instrument Never place any objects containing water on top of the instrument. Doing so can lead to malfunction. Do Not Apply Physical Shock or Vibration to the Instrument Do not apply physical shock or vibration to the instrument.
Page 36: Installing The Instrument
• It is possible to install the TA220 with the stand in the upright position. Please note that the instrument specifications are based on horizontal placement. When using the stand, pull the stand forward until it locks (perpendicular to the bottom surface of the instrument).
Page 37 3.2 Installing the Instrument Installation Location and Environment The instrument must be installed where the following conditions are met. Orientation and Stability Install the instrument in a stable, horizontal place. Accurate measurements may be hindered if the instrument is used in an unstable place or tilted position. Ventilation Inlet holes are located on the top and bottom of the instrument.
Page 38 80% RH whenever possible. Rack Mounting When rack mounting the TA220, use the rack mount kit that is sold separately. For the procedure on attaching the TA220 to a rack, see the User’s Manual included in the rack mount kit.
Page 39: Connecting The Power Supply
Maximum power consumption 150 VA * The TA220 can use a 100-V or a 200-V power supply. Check that the voltage supplied to the TA220 is less than or equal to the maximum rated voltage of the provided power cord (see page ii) before using it.

Page 43 Consequently, a correct waveform cannot be input to the measurement circuit of the TA220. The input capacity of each probe is not necessarily all the same. Therefore, the probe has a variable capacitor (trimmer) that allows the input capacity to be adjusted.
Page 44: Entering Numerical Values
Explanation You can set the numerical value within the range of each item. You can confirm that the TA220 is ready to accept numerical values when a single digit of the numerical value on the display is blinking. Note You can reset the specified numerical value to the initial value (factory default setting).
