tions. Ea ch ta sk refers you to the a ppropriate individual control byte for deta ils.


This section contains detailed explanations for each of the control bytes.

S113B, S114B, S331B, S332B PM 1




This programm ing ma nua l is w rit ten exclusively for th e Anritsu Site Ma ster Models S113B , S114B, S 331B,

an d S 332B w ith firmw ar e Version 1.42 and above. For informa tion on firmw ar e upgrade, please contact y our

loca l Anritsu service cent er.

General Description

The Site Master must first be set into “remote” mode for communication with a computer. Remote mode dif-

fers from normal repetit ive sw eep a nd single-sw eep modes. During r emote mode, the S ite Ma ster suspends

normal opera tions and a t t ends to the serial port . The front pa nel display indicat es when the S ite Mast er is

in remote mode.

Once in remote mode, you can send control bytes a nd a ssociat ed dat a to the Site Ma ster via the serial port .

These control byte sequences command the Site Master to perform various functions and activities. The se-

rial port supports virtually all features accessible from the keypad. The only exception is the printer, which

requires connection t o the sa me 9 pin connector on t he Site Mast er rea r pa nel.

To complete t he commu nicat ion session, send t he contr ol byte to exit remote mode. Sit e Mas ter r esumes nor-

mal operations. You may also exit the remote mode by using the escape key.

Cabling

Serial communicat ions t ake place via t he 9 pin connector on t he back of the Site Ma ster. The Site Ma ster is a

DTE-type serial device and therefore requires a “null modem” cable for communication with a computer,

wh ich is also a DTE device. We provide a suita ble cable w ith y our Site Ma ster.

Serial Communication ParametersThe Site Ma ster communicat es at a baud r at e of 9600. It uses no par ity bits, 8 da ta bits, an d 1 stop bit

(N-8-1). No hardware handshaking is used.

Communications Error Checking

Since there is no ha rdw ar e han dsha king, byte level error ha ndling must be done by the controlling program.

The expected n umber of response byt es for each control byt e (listed in th e cont rol byte d escription section of

this ma nua l) works w ell for responses coming from the Site Ma ster. For da ta strea ms going to the Site Ma s-

ter, the “wa tch dog t imer” protects a gainst interrupted tra nsmissions by a borting a control byte sequence if

the inter-byte time limit is exceeded.

Parameter Validation

The Site Ma ster va lidates input pa ra meters for each control byte sequence. I f the input pa ra meters a re out

of range or invalid, t he Site Ma ster notifies t he computer by sending P ar am eter Er ror B yte #224 (E0h). The

Site Mast er discar ds the received dat a a nd w ait s for the next contr ol byte.

Entering Remote Mode

Send t he Ent er Remote Mode byte #69 (45h) to the Site Ma ster t o enter r emote mode at the end of a sweep.

Send t he En ter R emote Mode Immediat ely byte #70 (46h) to enter remote mode in t he middle of a sweep.

The Site Ma ster’s serial port buffer is one byte w ide. No interna l buffer exists, so wa it ing is essential. I f the

Site Ma ster is n ot in remote, sending a second byte overw rites th e original byt e comma nding it to go into re-

mote. I f you send contr ol byte #69, you must w ait until t he end of the sw eep. If you send control byte #70, th e

unit w ill enter remote mode as it r eceives the byte. Note tha t t his means t he dat a st ored for th e current

sweep may be incomplete.

Once you receive the response string from Site Master, you’re in remote mode.

Exiting Remote Mode

Send t he Exit Remote control byte #255 (FFh) to the S ite Mast er. Sit e Mast er sends a response byte of

255 (FF h) then exits r emote mode.

Lifetime of Changes to Site Master Operating Parameters

Syst em para meters changed during r emote mode remain changed for normal opera tion. They a re not aut o-

ma tically w rit ten t o the non-volat ile EEP ROM. Turning off power erases t he changed sett ings.

If you wa nt t he changes saved, you must save th e cha nge to one of the setup memories. U se either t he

run-time setup (location 0, which holds the power-on defaults) or one of the ten saved setups. See control

byt e #18 (12h) for deta ils.

ited nu mber of read cycles. The w rit e cycle limita tion is for a specific loca tion. For exa mple, you ca n st oresetup #1 100,000 times an d set up #2 100,000 times, etc.

I t is f or t h is re a son w e d o n ot a u t o m a t ica l ly s t o re t h e ch a n g e d syst e m p a ra m e t ers t o E E P ROM . I n st e a d , we

provide a mea ns of cha nging the opera ting par am eters independent of this limita t ion.

Be aware of the EEPROM write cycle limitat ion when programming the Site Master. Keep the number of

wr ite cycles to a minimum.

Functional Description

INITIALIZE

Enter remotemode - see control byte #69 (45h)

Site Ma ster m ust be in remote mode for further contr ol byte comma nd sequences to be accepted.

Remember t o wa it unt il Site Ma ster responds before issuing further control byte sequences.

Enter remotemode immediately - see control byte #70 (46h)

CON F I G URE S YS T E M

Fixed CW mode control - see control byte #1 (01h)

Site Ma ster “dith ers” the C W signal for improved immunit y t o interfering signa ls. Turning on th e

fixed C W signal bit “cleans up” t he output spectrum by disa bling the dithering. The dra w back isdecreased immunit y to interfering signals.

Serial port echo - see contr ol byt e #10 (0Ah)

U se this to synchronize the S ite Mast er sw eep and computer requests for current tr ace dat a . This

feature is especially useful for synchronizing dist an ce to fault sw eeps.Site Master goes into single sweep mode. It sends the sweep complete byte #192 (C0h) after the com-

pletion of each sweep. You must send the sweep trigger byte #48(30h) for the Site Master to perform

another sweep. Retrieve the trace data using control byte #17 (11h).

Single sweep - see cont rol by te #11 (0B h)

This puts t he Site Ma ster int o single sweep mode. Normally t he Site Ma ster sw eeps continua lly.

Once in the single sweep mode, send the sw eep tr igger byte #48 (30h) to cause S ite Ma ster t o per-

form a nother sw eep.

Read failure counters -see contr ol byt e #22 (16h)

In order to provide absolute confidence a bout the va lidity of a measurement, interna l counters

monitor the analog integrator and phase lock loops for error conditions. If an error occurs, it is

logged. These counters perform th e sam e function a s th e icons on th e front panel.

Watch-dog timer On/Off - Control Byte #12 (0Ch)

D e sc r i p t i o n : Enables or Disables the Watch-dog timer.

The Site Master incorporates a Watch-dog Timer for higher reliability in serial communication. In selected

contr ol bytes (see contr ol byte summa ry), the Sit e Mast er checks for the t ime interval between each byt e re-

ceived from the computer. If the time interval exceeds the set time limit (0.5 sec), the Site Master notifies the

computer by sending Time-out Byte #238 (EEh). The Site Master discards the data it just received and then

wa its for the next contr ol byte sequence.

Sequence Site Master calibration - Control byte #13 (0Dh)

D e sc r i p t i o n : Init iates a calibration step.

The Site Mast er must be calibrat ed to give accura te measur ements. Ca libration is based on frequency range.

Once the frequency r an ge is set , sequence the calibrat ion process using th is control byte. Measur e each com-

ponent (OP EN, SH ORT, LOAD) then t rigger th e calculat e step. The calculate st ep uses the m easurements

obta ined and genera tes th e correction fa ctors.

U pon receiving this control byte any old calibrat ion da ta is lost . The Site Ma ster does the calibrat ion st ep

specified by the second byt e. After t he measur ements, you must trigger t he calculat ion st ep to complete the

calibration.

After receiving the calculat ion byt e, the S ite Ma ster checks to see if a ll three calibrat ion st eps a re completed.

The Site Ma ster calculates t he result ing correction fa ctors a nd sends a n Operat ion C omplete Byt e #255

(FFh ) to the computer. I f a ll t hree steps are not complete, the Site Ma ster r eturns a n Operat ion I ncompleteByte #224 (E0h) and no calculation is performed.
