Interface Control dialog box help

Handler IO Tab

Enable Handler Control Enables and disables sending data out the  Handler IO Connector. The enable is set independently per-channel and for "Before Sweep" and "After Sweep".

Ports A, B, C, D  Sends values to the respective Handler I/O port. Although ports C and D are normally bidirectional, ONLY Output mode is allowed using the Interface Control feature. It cannot read from these, or any other, ports.

Enable Control-All Channels  Enables and disables ALL Interface Control communication. When cleared (default setting) Interface Control is disabled and NO data is sent. To send data, the individual interfaces must also be enabled.

Channel Pulldown  This allows user to set IO independently for each channel.

Before Sweep/After Sweep Pull down  Allows setting IO data independently for before or after sweep. Default setting is Before sweep. Before sweep is used to set up command before making a measurement. After Sweep is used to return SSA to a safe state so that the next channel does not have any problems.

Dwell Entry Delay time between all commands sent and measurement start. Set independently per channel and for forward and reverse sweep, not set per IO type. This is used to allow all external devices to settle before making a measurement.

For save or recall, refer to Instrument State Save.

DIO1/ DIO2 Tabs (Device Test I/O)

Digital 16-bit IO is composed of 2 independent sets of Digital 8-bit IO. See the Device Test IO in Rear Panel I/O.

The DUT Control function provides 2 different type of controls for user DUT. These are “parallel IO control” and “MIPI RFFE control”. The analyzer can provide 2 sets of 8-bit digital IO. A 8-bit digital IO has up to 8-line parallel IOs, and up to 4 MIPI RFFE controllers, and user can set mixed configuration of parallel IO and MIPI RFFE with some limitations.

The DUT Control signal generation timing is basically same as Control Lines control of External Testset, so the function design is based on the External Testset control.

Enable DIO1/DIO2  Enables and disables sending data out the 8-bit digital IO (Device Test I/O).

IO Level Set voltage level of "Power Output" pin of the 8-bit IO. The power out pin is used as VIO of RFEE. This level determine the "HIGH" logic level of all IO pins of the 8-bit IO. The value range is 0.9V to 3.5V with 0.05V resolution.

Type  Eight IO pins are consists of 4 group of 2-pins pair: (Pins No. 1 and 2), (Pins No. 3 and 4), (Pins No. 5 and 6), (Pins No. 7 and 8). Each group can be assigned with Parallel or RFFE by using the pull-down box.

Name The name of assigned signal.

State Control buttons are displayed depending on Type selection, either Parallel or RFFE.

• When Parallel is selected:

• In or OUT -  Select the pin function from Input or Output.

• Low or High - For input pin, show the current state. For output pin, select the level from Low or High

• When RFFE is selected:

• Clicking RFFE setup..  shows the RFFE setup dialog box.

Warning: Users can save or recall IO settings as a state file. So users need to take care not to damage the DUT if they use state files.

Macro Tab

Enable Macro Enables and disables sending commands out the GPIB or VISA interface.

SCPI Commands The multi-line edit control accepts pairs of GPIB or VISA address and SCPI command. The SCPI commands are sent to the GPIB or VISA addresses before the first trace on the channel begins sweeping.

Macro File- Path The single-line edit control accepts a file path to a macro. The macro is executed before the first trace on the channel begins sweeping. The firmware just waits for the end of the macro and does not care errors occurring in the macro. The macro designer is responsible for error handling if necessary.

Macro File- Parameters  The single-line edit control accepts parameters to execute macro.

App IO Tab

Note: See :CONTrol:SIGNal:AIO:PIN:FUNCtion.

Enable Control-All Channels, Before Sweep, Dwell  These controls are disabled.

Function  When a white cell is clicked, a drop down list appears to show functions assignable to the specified port. Refer to the command description about “:CONTrol:SIGNal:AIO:PIN<pin>:FUNCtion <func>” for the assignable functions. If “CHANNEL_CTRL” is specified, different functions can be assigned per channel.

All Channels  When a channel is selected in the channel scope dropdown, the dialog switches to channel mode as shown in the figure below. Functions can be assigned to the ports for which “CHANNEL_CTRL” has been specified in the global mode.

RFFE Setup dialog box help

Clock Rate  Specify the clock rate from 25 kHz to 25 MHz. Possible values are 50000/n, with integer n, 2000 to 2.

RFFE 1-4 Tabs

#  RFFE command sequence number up to 16

Slave Addr  Specify the slave address in decimal. The slave address should be from 0 to 15 (4 bits).

Command Type  Select the RFFE command sequence type.

• R0Write: Register 0 Write

• RREad: Register Read

• RWRite: Register Write

• ERRead: Extended Register Read

• ERWRite : Extended Register Write

Byte Count  Specify byte count value in decimal. The value range is depending on command sequence type setting.

Addr Specify the address value in hex Integer value. The value range is coupled with command sequence type setting.

Data  Specify or read the data in hex value. Comma separated of data values. The value length is coupled with byte count setting.

Parity  The Parity field is valid if Byte Count is Register Read or Extended Register Read. Show the parity bit value for each data byte.

Add Adds one line of RFFE command to the table.

Delete Deletes one line of RFFE command from the table.

OK Applies the settings of the DUT control related parameters and closes the DIO RFFE Setup dialog and back to Interface Control dialog .

Cancel  Does not apply changes that were made, and closes the  DIO RFFE Setup dialog and back to Interface Control dialog..

Apply Will apply all settings from within the dialog.
