Programming Overview

NOTE: This programming manual is written exclusively for the Anritsu Spectrum Master MS2711D. For information on firmware upgrades, contact your local Anritsu Service Center. Commands listed in this manual are not all backward-compatible with earlier Anritsu models.

General Description

The Spectrum Master must first be set into “remote” mode for communication with a computer. Remote mode differs from normal repetitive sweep and single-sweep modes. During remote mode, the Spectrum Master suspends normal operations and attends to the serial port. The front panel display indicates when the Spectrum Master is in remote mode.

Once in remote mode, a series of control bytes and associated data are sent to the Spectrum Master to perform various func tions and activities. The serial port supports virtually all features accessible from the keypad with the exception of the printer. The printer requires connection to the same 9-pin connector on the Spectrum Master rear panel used for remote com munication.

To complete the communication session, send the control byte to exit remote mode and the Spectrum Master will resume nor mal operations. You may also exit the remote mode by pressing the ESCAPE/CLEAR key on the Spectrum Master front panel.

Interface Cable Installation

The Spectrum Master is a DTE-type serial device. Communication between the Spectrum Master and a PC is accomplished over a null modem serial cable provided with the Spectrum Master (Anritsu part number 800-441). Connect the cable to the Serial Interface connector on the Spectrum Master test connector panel and to the appropriate COM port connector on the PC.

Serial Communication Parameters

The Spectrum Master begins communication at 9600 bps when first powered on. It uses no parity bits, 8 data bits, and 1 stop bit (N-8-1). No hardware handshaking is used. The Set Baud Rate Control Byte #197 (C5h) serial command can be used to change the baud rate to 19,200, 38,400, 56,000 or 115,200. An invalid setting returns the rate to 9600.

Communications Error Checking

Since there is no hardware handshaking, byte level error handling must be done by the controlling program. Use the expected number of response bytes (listed in the control byte description section of this manual) when waiting for feedback from the Spectrum Master. For data streams going to the Spectrum Master, the “watch dog timer” protects against interrupted trans missions by aborting a control byte sequence if the inter-byte time limit is exceeded.

Parameter Validation

The Spectrum Master validates input parameters for each control byte sequence. If the input parameters are out of range or invalid, the Spectrum Master notifies the computer by sending Parameter Error Byte #224 (E0h). The Spectrum Master dis cards the received data and waits for the next control byte.

Entering Remote Mode

Send the Enter Remote Mode Byte #69 (45h) to the Spectrum Master to enter remote mode at the end of the current sweep. Send the Enter Remote Mode Immediately byte #70 (46h) to enter remote mode in the middle of a sweep.

The Spectrum Master serial port buffer is one byte wide. No internal buffer exists, so waiting for the response from the unit is essential. If the Spectrum Master is not in remote mode, sending a second byte overwrites the original byte commanding it to enter remote mode. If control byte #69 is sent, the Spectrum Master will enter remote mode at the end of the current sweep. If control byte #70 is sent, the unit will enter remote mode as soon as it receives the byte. This means that data stored for the

Spectrum Master PM 1

Page 7

current sweep may be incomplete. Once a response string is received from the Spectrum Master, the unit is ready to accept additional control bytes.

Exiting Remote Mode

To exit remote mode, send the Exit Remote Control byte #255 (FFh) to the Spectrum Master. The Spectrum Master sends a response byte of 255 (FFh) then exits remote mode. Remote mode can also be exited by pressing the ESCAPE/CLEAR front panel key.

Remote Mode Changes to Spectrum Master Operating Parameters

System parameters changed during remote mode remain changed for normal operation after the unit exits remote mode. However, the changes are not automatically written to the non-volatile EEPROM. Turning off the Spectrum Master power erases the changed settings.

To retain the changes, the setup must be saved to one of the setup memory locations. Use either the run-time setup location 0, (which holds the power-on defaults) or one of the nine other setup locations. Control byte #64 (40h) sets the auto-save flag which commands the Spectrum Master to automatically save the changes to the run-time setup location upon exiting remote mode. See the Spectrum Master User’s Guide or information in this manual on control byte #18 (12h) for further details.

Write Cycle Limitation of EEPROM

The EEPROM, used to store calibrations, setups and traces has a guaranteed lifetime of at least 100,000 write cycles and an unlimited number of read cycles. The write cycle limitation is for a specific location. For example, setup #1 can be stored 100,000 times and setup #2 can be stored 100,000 times, etc. Because of this, the Spectrum Master does not automatically store the changed system parameters to the EEPROM. Be aware of the EEPROM write cycle limitation when programming the Spectrum Master and keep the number of write cycles to a minimum.

Documentation Conventions

Throughout this manual, the following conventions will be observed:

Numeric Representation

Hexadecimal numbers are represented with the suffix h. For example, the decimal number 255 is represented in hexadecimal as FFh.

Binary numbers are represented with the suffix b. For example, the decimal number 2 is represented in binary as 10b. Decimal numbers are represented with the prefix # when referring to a control byte (command byte) and without a prefix or

suffix in all other cases.

Bit Positions

When enumerating bits in a byte, bit 0 will always be the least significant bit (LSB).

Mode References

The term “SPA” in reference to a command denotes Spectrum Analyzer mode. All other modes are referenced individually.

The current time setting can be found by using control byte #33 to recall trace 0 and examining response bytes 31-38.

The current date setting can be found by using control byte #33 to recall trace 0 and examining response bytes 21-30.

Set Reference Number – Control Byte #9 (09h)

Description: Stores a Reference Number with the sweep trace.

The reference number is also known as the trace name. It is any combination of 16 letters, numbers and the characters “-“, “,”, “.” and “+”. This command stores a trace name with the sweep trace.

The current reference number is found by recalling trace 0 and examining response bytes 39 to 54.

Serial Port Echo On/Off – Control Byte #10 (0Ah)

Description: Sets the serial port echo mode On/Off.

Serial Port Echo Mode uses the single sweep mode (see control byte #108 (6Ch)). At the end of each sweep cycle, the Spectrum Master sends a Sweep Complete Byte #192 (C0h) to the serial port.

This mode activates once the Spectrum Master exits from the remote mode. Serial Port Echo status can’t be saved to or recalled from saved setups. Cycling power resets the Serial port echo status to Off.

The Serial Port Echo Mode allows run-time handshaking between the Spectrum Master and computer by doing the following:

8 Spectrum Master PM

Page 14

1) Enter remote mode. Set Serial Port Echo Mode On. Exit remote mode.

2) The Spectrum Master sweeps once and then sends the Sweep Complete Byte.

3) After you receive it. Enter remote mode. Recall sweep 0 (last sweep trace in RAM).

4) Exit remote mode. Send Sweep Triggering Byte #48 (30h) and wait for the next sweep cycle.

5) Repeat steps 2-4

Watch-Dog Timer On/Off – Control Byte #12 (0Ch)

Description: Enables or disables the Watch-dog timer. Default is Disabled.

The Spectrum Master incorporates a watch-dog timer for higher reliability in serial communication. In selected control bytes (see Control Byte Summary), the Spectrum Master checks for the time interval between each byte received from the computer. If the time interval exceeds the set time limit (0.5 sec), the Spectrum Master notifies the computer by sending Time-out Byte #238 (EEh). The Spectrum Master discards the data it just received and then waits for the next control byte sequence.

NOTE: This command exists for backward compatibility with MS2711B models. To access the new fea

tures, use Control Byte #33 (21h). This command cannot be used with a frequency converter module (Option 6 required) attached.

Description: Queries the Spectrum Master for sweep trace data.

Note: Before you can recall a sweep stored in non-volatile memory (trace numbers 1-200) you must build a trace table in the

Spectrum Master’s RAM. Use Control Byte #24 to build the trace table. Since the trace table exists in RAM, Control Byte #24 must be executed every time the Spectrum Master’s power is cycled.

NOTE: This command exists for backward compatibility with the MS2711B. To access the new features use Control Byte #29 (1Dh). This command cannot be used with a frequency converter module (Option 6 required) attached.

Description: Queries the Spectrum Master for current system settings.

The current state of the Spectrum Master represents the state after the last successful remote control operation. For example, change the start frequency to another valid frequency while in remote mode, then execute control byte #29. The new start frequency will be returned in bytes 4-7, even though no sweep has been performed with that frequency.

Query System Status – Control Byte #29 (1Dh)

NOTE: This command is new to the MS2711D. Use it instead of Control Byte #20 to access new fea tures.

Description: Queries the Spectrum Master for current system settings. Unlike Control Byte #20, this command returns only data that is valid for the active mode, plus system settings, such as the defined printer.

The current state of the Spectrum Master represents the state after the last successful remote control operation. For example, change the start frequency to another valid frequency while in remote mode, then execute control byte #29. The new start frequency will be returned in the defined bytes, even though no sweep has been performed with that frequency.

Recall Sweep Trace – Control Byte #33 (21h)

NOTE: This command is new to the MS2711D. Use it instead of Control Byte #17 to access new fea tures.

Description: Queries the Spectrum Master for sweep trace data.

NOTE: Before you can recall a sweep stored in non-volatile memory (trace numbers 1-200) you must build a trace table in the Spectrum Master’s RAM. Use Control Byte #24 to build the trace table. Since the trace table exists in RAM, Control Byte #24 must be executed every time the Spectrum Master’s power is cycled.

Sweep Data Echo On/Off - Control Byte #49 (31h)

Description: Sets the sweep data echo mode On/Off.

Sweep Data Echo Mode behaves much like the Serial Port Echo Mode (see Control Byte #10). It automatically puts the unit into single sweep mode. At the end of each sweep cycle, the Spectrum Master sends a Sweep Complete Byte #192 (C0h) to the serial port. At this time, sweep data can be queried (see Control Byte #33) without having to enter remote mode first or exit remote mode when done. Depending on the value of the second following byte, the next sweep can be automatically triggered after the sweep data has been sent.

This mode activates once the Spectrum Master exits from the remote mode. Sweep Data Echo status can not be saved to or recalled from saved setups. Cycling power resets the Sweep Data Echo status to Off.

The Sweep Data Echo Mode allows run-time handshaking between the Spectrum Master and computer by doing the following:

1) Enter remote mode. Set Sweep Data Echo Mode On. Exit remote mode.

2) The Spectrum Master sweeps once and then sends the Sweep Complete Byte.

3) After you receive it: Recall sweep 0 (last sweep trace in RAM).

4) If using auto triggering, repeat steps 2-3. If using manual triggering, go to step 5.

5) Send Sweep Triggering Byte #48 (30h) and wait for the next sweep cycle.

6) Repeat steps 2-5.

NOTE: To execute commands other than #33, you must use the traditional Enter Remote, Send Commands, Exit Remote communication sequence.

Description: Enter remote mode at the end of a sweep then send model number and firmware version to the computer.

The computer sends Enter Remote mode byte #69 (45h) to the Spectrum Master and waits for response.

Since the Spectrum Master polls its serial port buffer at the end of each sweep, the computer must wait until the Spectrum Master sends the return bytes before sending a new control byte. Otherwise, the new control byte overwrites the old one (saying enter remote) and the Spectrum Master does not respond as expected.

Once in remote mode, the Spectrum Master stops sweeping. A Remote Mode Indicator appears on the LCD.

The Spectrum Master sends its model and software version numbers to the computer. The Spectrum Master is now able to take multiple control bytes. It waits for the next control byte.

Enter Remote Mode Immediately – Control Byte #70 (46h)

Description: Enter remote mode in the middle of a sweep, then send the model number and firmware version to the computer.

The computer sends Enter Remote Mode Immediately byte #70 (46h) to the Spectrum Master and waits for a response. This control byte causes the unit to enter remote mode immediately. Note that this could result in incomplete sweep data. Use control byte #69 if complete data is required.

335 Refer to Control Byte #3 “Select Measurement Mode” for valid measurement modes.

Set Spectrum Analyzer Multiple Limit – Control Byte #113 (71h)

Description: Sets the position and ON/OFF Status of a limit segment.

Multiple limits are defined by multiple limit segments, each with a different finite slope. The single limit is a single, horizontal line that can be defined to act as an upper limit or as a lower limit. See control byte #103 for information about the single limit.

The limit types are mutually exclusive. That is, you cannot have both single and multiple limits at the same time. Note that setting a limit segment ON automatically makes the limit type "MULTIPLE."

One segment is defined each time this command is sent to the Spectrum Master. The first two bytes of the command specify which segment is being defined. There are 5 upper limits and 5 lower limits available in Spectrum Analyzer mode. Byte 1 selects the segment number. Byte 2 specifies whether it is an upper limit or a lower limit. Byte 3 turns the segment ON or OFF. Byte 4 specifies whether the error beep sounds when the bound set by the segment is exceeded by the measured data.

The segment location is defined by its endpoints. The "Start" endpoint must appear to the left of the "End" endpoint on the graph. That is, Start X < End X. If Start X = End X then Start Y must equal End Y. Vertical segments are not allowed.

Bytes to Follow: 20 bytes

Set Reference Level Offset – Control Byte #115 (73h)

Description: Set the value of the reference level offset.

The reference level offset allows the user to view the result of trace math (A+B, A-B) even if it is greater than +20 dBm or less than –120 dBm. The offset is a constant that is subtracted from the reference level.

Note that the valid range is –100 to +100 dB.

Send the value as (value in dB * 1000) + 270,000.

For example, to compensate for a 30 dB attenuator, the reference level offset should be –30 dB. That value would be sent over the serial port as (–30 * 1000) + 270,000 = 240,000.

Set Spectrum Analyzer Impedance - Control Byte #116 (74h)

Description: Set the impedance and the loss value due to an adapter.

The MS2711D can automatically compensate for the effects of impedance adapters. The impedance of the MS2711D is 50W, so there is no need for an adapter in this case. The loss for the Anritsu 75W adapter 12N50-75B is known by the MS2711D.

This control byte also allows for the specification of the impedance and the loss due to an adapter the system does not know. In either case, 5 bytes must be sent to the unit. If the impedance is 50W or one of the known adapters is specified, bytes 2-5 are ignored. If an unknown adapter is specified, the unit uses bytes 2-5 to correct for the adapter.

Exit Remote Mode – Control Byte #255 (FFh)

Description: Spectrum Master exits remote mode.

The computer sends the Exit Remote command #255 (FFh) to the Spectrum Master. Spectrum Master returns a confirm flag (FFh). The Spectrum Master resumes sweeping, either continuously or singly.

You may also press the “ESCAPE” key on the Spectrum Master key pad to exit from remote mode (given that the serial communication is still in sync). In this case, the Spectrum Master does not return a confirm byte to the serial port.

When exiting remote mode, system parameters changed during remote mode are used immediately.

System parameters changed during remote mode are not written to the non-volatile EEPROM.

You may want to save the changes to the run-time setup (saved setup location 0, which holds the power-on setup) or one of the saved setups for the current measurement mode. See control byte #18 (12h) for details.
