Chapter 1 I2C-Bus Signal Analysis Function

1.1 Overview of the I2C-Bus Signal Analysis Function

About the I2C-Bus Signal Analysis Function

By using this function, you will be able to analyze data while displaying the I2C-bus signal waveform. The main functions are as follows:

• Trigger Function

Captures signals using various trigger conditions such as when a start condition is detected, when an Acknowledge bit is not detected, when the specified address (7 bits + R/W) pattern is met, or when the data pattern is met or not met (start trigger, Non-Ack trigger, or address trigger). Triggers can also be activated by combining the I signal) and the CH3/CH4 signal (combination trigger).

• Analysis Function

You can analyze the data and other information that are displayed when the acquisition of historical data, acquisition data, or waveform is stopped. The analysis results are listed on the right side of the screen. In addition, the analysis results can be displayed using hexadecimal and binary notation. The analysis results and waveforms can be displayed simultaneously.

• Search Function

From the acquired data (the currently displayed data), you can search in the forward or reverse direction for data that matches a specified address pattern, data pattern, or Acknowledge bit condition, and display the matched data expanded on the ZOOM display. You can specify the address pattern or data pattern using binary or hexadecimal values. You can also search indefinite data.

1.2 Connecting the Probe

Input Terminals

Connect the probe to one of the input terminals located at the lower section of the front panel. The input impedance is 1 MΩ±1.0% and approximately 28 pF.

1MΩ 28pF 300V

CAT

WARNING

To prevent fire or electric shock, do not use this instrument for category II, III, or IV measurements.

CAUTION

The maximum input voltage for 1 MΩ input is 300 VDC or 300 Vrms when the frequency is 1 kHz or less. Applying a voltage exceeding this maximum can damage the input section. If the frequency is above 1 kHz, the input section may be damaged even when the voltage is below this value.

Precautions to Be Taken When Connecting a Probe

• When using the I2C-bus trigger function, apply the SCL (serial clock) signal and SDA (serial data) signal to the CH1 and CH2 input terminals, respectively.

• When connecting a probe to the instrument for the first time, perform phase correction of the probe as described in section 3.5, “Compensating the Probe (Phase Correction)” in the to do so may result in unstable gain across different frequencies, thereby preventing correct measurement. Calibration must be performed for each channel.

• Note that if the object being measured is directly connected to the instrument without using a probe, correct measurements may not be possible due to loading effects.

1.3 Setting the Trigger Conditions

Setting the Address Trigger

When the trigger type is set to “ADRS,” a trigger can be activated when the combination of the following three trigger conditions is met.

• Address Pattern: Set the 7-bit address and the R/W bit. A trigger is activated when the 7-bit address and the R/W bit matches the specified pattern.

• Data Pattern: Set an 8-bit data pattern. When the position is set to “First Byte,” compares to the byte immediately following the address and activates a trigger on a match. When the position is set to “Anywhere,” seaches until a match is found.

The trigger conditions can be specified using binary or hexadecimal values. Determines whether the data matches the specified conditions in the following order: “Address Pattern,” and “Data Pattern.” When all conditions are met, a trigger is activated. For the combination of settings, see section 1.4, “Trigger Setting Examples.”

Note

If there is at least one “X” bit in a group of four bits in the binary display, the corresponding hexadecimal display will show an “X.”

• Setting the Data Pattern Condition

Select the condition from the following. The condition can be specified on Data1 Pattern and Data2 Pattern, separately.

• True: Activates a trigger when the specified pattern is met.

• False: Activates a trigger when the specified pattern is not met.

C-Bus Signal Analysis Function

• Setting the Data Pattern Posotion

You can select the location of the byte data for comparison with the data pattern.

• First Byte: Compares with the first byte after the address.

• Anywhere: Compares bytes after the address until a match is found.

• Setting Whether to Ignore Restart Conditions

You can select whether to ignore the restart condition that occurs after starting the trigger detection upon detecting the Start condition.

• Yes: Ignores the restart condition and continues with the trigger detection.

• No: Restarts the trigger detection when a restart condition is detected.

• Setting Whether to Ignore Start/Stop Conditions That Do Not Conform to the

Protocol

You can select whether or not to ignore the start or stop condition that occurs in the middle of the address or data bit while detecting the trigger.

• Yes: Ignores the start/stop condition and continues with the trigger detection.

• No: Restarts or stops the trigger detection when a start/stop condition is detected.

Explanation

Analyzing Data

Setting the Analysis Conditions

Analyzes the data of CH2 or CH4 by setting CH1 or CH3 to a clock channel.

• Setting the Clock Channel

45. Press the Prev soft key to search data existing before the current position. Press the Next soft key to search data existing after the current position. When a match is found in a pattern search, the corresponding data in the analysis result display on the right side of the screen is highlighted, and the ZOOM display moves accordingly. In an indefinite data search, Data of the analysis number in which indefinite data is present is highlighted.

Set the clock channel to CH1 or CH3. When the clock channel is set to CH1, the data channel is CH2; when the clock channel is set to CH3, the data channel is CH4.

Setting the Level

Set the level used to determine the rising or falling edge of the clock signal. Selectable range: 8 divisions within the screen Resolution: 0.01 divisions (For example, the resolution for 2 mV/div is 0.02 mV.)

Setting the Hysteresis

Selectable range: 0.3 divisions to 4.0 divisions

• Setting the Data Channel

Set the data channel to CH2 or CH4. When the data channel is set to CH2, the clock channel is CH1; when the data channel is set to CH4, the clock channel is CH3.

Setting the Threshold Level

Set the level used to determine the data channel signal level (0, 1, or indefinite). Thr Upper: Signal exceeding this level is determined to be 1. Thr Lower: Signal below this level is determined to be 0. If Thr Lower ≤ data signal level ≤ Thr Upper, the signal level is determined to be “indefinite data.” If indefinite data is found, “*” is displayed in the hexadecimal display box at the byte where the indefinite data exists on the display screen of analysis results.

1.5 Analyzing/Searching Data

Items to Be Analyzed

The following data can be analyzed:

• Historical data.

• Data that are displayed when the waveform acquisition is stopped.

• Loaded acquisition data (ACQ data). Analysis is performed only on the waveform selected by “Select Record” for historical data.

Analysis Range

Analysis is performed on the acquisition data within the display screen. Up to 40000 bytes of the analysis results can be displayed. The displayed result varies depending on the number of bytes analyzed as follows:

• When the total analysis result is less than or equal to 40000 bytes

All points are displayed regardless of the position of the Reference Point.

• When the total analysis result is greater than 40000 bytes

The displayed result varies depending on the number of analysis results on the Pre* and Post* sides as follows:

• When the Pre side = 30000 and the Post side = 30000 → Pre side = 20000 and

Post side = 20000

• When the Pre side = 10000 and the Post side = 50000 → Pre side = 10000 and

Post side = 30000

• When the Pre side = 50000 and the Post side = 10000 → Pre side = 30000 and

Post side = 10000

C-Bus Signal Analysis Function

* Pre: Start from the reference point and display back (to the left)

Post: Start from the reference point and display forward (to the right)

Notes When Performing Analysis

• Analysis and search cannot be performed while the waveform acquisition is started.

• Analysis and search cannot be performed on accumulated waveforms.

Executing the Analysis

When analysis is performed, the results are listed on the right side of the screen.

• List of Analysis Results

The following items are displayed. No.: Up to 40000 points can be displayed. Hex: The analyzed data is displayed using hexadecimal notation. However, if a byte

of data is less than 8 bits, the data is not displayed. If indefinite data exists, “*” is displayed. Indefinite data is considered the same value as the previous bit for the analysis. If the first data is indefinite, it is considered 0 for the analysis.

Ack: Displays the Acknowledge bit condition.

Note

If you execute the analysis and select (highlight) an arbitrary byte in the list of analysis results, the Zoom Position moves to the head of that byte. In addition, if you move the Zoom Position, the highlighting moves to the corresponding byte in the list of analysis results.

Set the byte pattern to be searched in binary or hexadecimal notation. You can set the address pattern, data pattern, and Acknowledge bit condition. Bits set to “X” are not searched.

Note

If there is at least one “X” bit in a group of four bits in the binary display, the corresponding hexadecimal display will show an “X.”

• Indefinite Data Search (Indefinite State)

Searches indefinite data from the analysis result. You cannot perform a pattern search and an indefinite data search simultaneously.

1-24

Note

Indefinite data is always considered matched to the specified status.

Executing the Search

Searches data that matches the specified search condition in forward (Prev) and reverse (Next) directions. When the data matches the search pattern, the corresponding data in the detailed analysis display on the right side of the screen is highlighted. In addition, the matched data is displayed expanded in the ZOOM display.

Chapter 2 SPI Bus Signal Analysis Function

2.1 Overview of the SPI Bus Signal Analysis Function

About the SPI Bus Signal Analysis Function

By using this function, you will be able to analyze data while displaying the SPI bus signal waveform. The main functions are as follows:

• Analysis Function

You can analyze the data and other information that are displayed when the acquisition of historical data, acquisition data, or waveform is stopped. The analysis results are listed on the right side of the screen. In addition, the analysis results can be displayed using hexadecimal or binary notation. The analysis results and waveforms can be displayed simultaneously.

• Search Function

From the acquired data (the currently displayed data), you can search in the forward or reverse direction for data that matches a specified data pattern and display the matched data expanded on the ZOOM display. You can specify the data pattern using binary or hexadecimal values and set the data length to a value between 1 and 8 bytes. You can also search indefinite data.

SPI Bus Signal Analysis Function

Chip select signal (CS)

Analysis result

Byte number: 0 Data output signal: 08(HEX) Data input signal: C4(HEX) Chip select signal: L Bit order: MSB First

Note

• On the DL1640/DL1640L, the clock signal is input to CH1; the data input signal (Data1 and Data2) to CH2 and CH3; and the chip select signal (CS) to CH4.

• Data is transmitted in units of bytes (8 bits) by synchronizing to the clock signal. Consequently, the SPI signal is analyzed or searched at the byte level.

• The SPI bus analysis function does not have a dedicated trigger.

2.2 Connecting the Probe

Input Terminals

Connect the probe to one of the input terminals located at the lower section of the front panel. The input impedance is 1 MΩ±1.0% and approximately 28 pF.

1MΩ 28pF 300V

CAT

WARNING

To prevent fire or electric shock, do not use this instrument for category II, III, or IV measurements.

CAUTION

Precautions to Be Taken When Connecting a Probe

• When performing SPI bus signal analysis, connect the signals to the input terminals as follows:

CH1: Clock signal CH2: Data input/output signal (Data1) CH3: Data input/output signal (Data2) CH4: Chip select signal (CS)

2-2

* CH2 and CH3 can be connected to either the data input signal or the data output signal. The

DL1640/DL1640L handles the data of the signal connected to CH2 and CH3 as Data1 and Data2, respectively.

• When connecting a probe to the instrument for the first time, perform phase correction of the probe as described in section 3.5, “Compensating the Probe (Phase Correction)” in the

DL1620/DL1640/DL1640L User’s Manual IM 701610-01E

. Failure to do so may result in unstable gain across different frequencies, thereby preventing correct measurement. Calibration must be performed for each channel.

• Note that if the object being measured is directly connected to the instrument without using a probe, correct measurements may not be possible due to loading effects.

Setting the Trigger Level

Selectable range: 8 divisions within the screen Resolution: 0.01 divisions (For example, the resolution for 2 mV/div is 0.02 mV.)

Setting the Trigger Slope

Select how the trigger source is to cross the specified level for activating the trigger from the following three choices. To activate the trigger on the edge falling of the CS signal (CH4), set the trigger slope to

: Trigger when the signal changes from below the trigger level to above the trigger

level (rising)

: Trigger when the signal changes from above the trigger level to below the trigger

level (falling)

: Trigger on either the rising or falling edge.

Setting the Trigger Coupling

Select the trigger coupling from the following. To activate the trigger on the edge falling of the CS signal (CH4), set the trigger coupling to DC. AC: Uses a signal that is obtained by removing the DC component from the trigger

source signal.

DC: Uses the trigger source signal as-is.

• Setting Data1 (CH2) and Data2 (CH3) Setting the Threshold Level

Set the level used to determine the data channel signal level (0, 1, or indefinite). Thr Upper: Signal exceeding this level is determined to be 1. Thr Lower: Signal below this level is determined to be 0. If Thr Lower ≤ data signal level ≤ Thr Upper, the signal level is determined to be “indefinite data.” If indefinite data is found, “*” is displayed in the Data1 or Data2 display box at the byte where the indefinite data exists on the display screen of analysis results.

SPI Bus Signal Analysis Function

• Setting the Chip Select Signal (CS)

To set the CS signal, specify CH4.

Setting the Level

Set the level used to determine whether the CH4 signal is high or low as follows: Selectable range: 8 divisions within the screen Resolution: 0.01 divisions (For example, the resolution for 2 mV/div is 0.02

mV.)

Selecting the CS Signal State (Enable State)

Select the state from the following: H: Analyzes the data input/output signal when the CS signal is high. L: Analyzes the data input/output signal when the CS signal is low. X: All data input/output signals are analyzed. The byte boundary of the analyzed

signal is the point where the CS signal changes from high to low or low to high.

–: This can be used when the CS signal is not selected. All data input/output signals

are analyzed. The data input/output signal that is delimited byte-wise is analyzed from the Reference Point.

2.4 Analyzing/Searching Data

Analysis Range

• When the total analysis result is less than or equal to 40000 bytes All points are displayed regardless of the position of the Reference Point.

• When the total analysis result is greater than 40000 bytes The displayed result varies depending on the number of analysis results on the Pre

and Post* sides as follows:

• When the Pre side = 30000 and the Post side = 30000 → Pre side = 20000 and

Post side = 20000

• When the Pre side = 10000 and the Post side = 50000 → Pre side = 10000 and

Post side = 30000

• When the Pre side = 50000 and the Post side = 10000 → Pre side = 30000 and

Post side = 10000

Pre: Start from the reference point and display back (to the left) Post: Start from the reference point and display forward (to the right)

Notes When Performing Analysis

• Analysis and search cannot be performed while the waveform acquisition is started.

• Analysis and search cannot be performed on accumulated waveforms.

SPI Bus Signal Analysis Function

Executing the Analysis

When analysis is performed, the results are listed on the right side of the screen.

• List of Analysis Results

The following four items are displayed. No.*: Up to 40000 points can be displayed. Dt1 and Dt2: The data of Data1 and Data2 is displayed using hexadecimal notation.

However, if a byte of data is less than 8 bits, the data is not displayed. If indefinite data exists, “*” is displayed. Indefinite data is considered the same value as the previous bit for the analysis. If the first data is indefinite, it is considered 0.

CS: Displays the CS signal state. Displays blank when the CS signal is not

set. Displays “H” or “L” when the CS signal is set.

Depending on whether the CS signal is set, the 0th byte varies as follows:

Searching Data

2.4 Analyzing/Searching Data

Setting the Search Conditions

• Pattern Search (Frame Pattern)

You can specify a data pattern of Data1 or Data2 in units of bytes and search the waveform. When a waveform that matches the specified pattern is found, the Zoom Position moves to that point and displays the searched waveform in the Zoom window. Set the pattern to be searched in binary or hexadecimal notation. Bits set to “X” are not searched. The items to be specified are as follows: Pattern Format: Specify the pattern display format. Select Hex (hexadecimal

display) or Bin (binary display).

Source: Set the target waveform to perform the pattern search to Data1 or

Data2. Data Byte: Set the number of data bytes from 1 to 8 (bytes). Data Pattern: Set the search pattern using hexadecimal or binary format. The bit

order is set to the format that was specified for the analysis. If the

specified bit contains an X, it is displayed as “$” in hexadecimal

format.

• Indefinite Data Search (Indefinite State)

Searches indefinite data from the analysis result. You cannot perform a pattern search and an indefinite data search simultaneously.

SPI Bus Signal Analysis Function

Note

• Indefinite data is always considered matched to the specified status.

• If analysis is performed on a channel of which a CS signal is selected, the data is considered

to be delimited at the point where the state of the CS signal changes. In this case, data search is also performed by considering the data to be delimited at that point. For example, when a 5-byte data shown in the following figure is analyzed, the search operation varies depending on the CS channel specification during the analysis.

• When analysis is performed by specifying a CS channel Data search across two CS intervals cannot be performed. Therefore, search is not possible by setting Data Byte to 4 or 5. (Cannot conclude from the analyzed data.)

• When analysis is performed without specifying the CS channel Independent of the chip select interval. Search can be performed by setting Data Byte to 4 or 5. Example (Enable State = L)
