·

InstaCal Module, part number ICN50

·

20 dB offset, Anritsu SC5270

·

6 dB offset, Anritsu SC5237

b. Procedure

NOTE

If performing full verification over the entire

frequency range with both an S114C and

S332C Site Master, perform this procedure

first on the S114C and then on the S332C.

1. Press and hold the

ESCAPE/CLEAR key,

then press the

ON/OFF key to turn on the

Site Master. (This sets the instrument to

the factory preset state.)

NOTE

Before continuing, allow a five minute warm

up for the internal circuitry to stabilize.

2. Press the

MODE soft key.

3. Use the Up/Down arrow key to highlight

RETURN LOSS, then press ENTER.

4. Press the

START CAL key. The message

“CONNECT OPEN or InstaCal TO RF

Out PORT” will appear in the display.

5. Connect the InstaCal module to the RF

Out port and press the

ENTER key.

NOTE

If this particular InstaCal module has been

used to calibrate this Site Master before, the

Site Master senses the familiar InstaCal

module and automatically calibrates the unit

using the OSL procedure.

If the Site Master senses that the

characterization data for the InstaCal module

connected to this Site Master is different than

the one currently stored, it will display soft

key options to keep or replace the InstaCal

characterization data.

Selecting the

YES soft key transfers all of the

characterization data from this InstaCal

module to the Site Master. The transfer may

take up to three minutes. This option is

preferred if this InstaCal module is to stay

with this particular Site Master. Once

completed, the data will not need to be

transfered again for this combination of Site

Master and InstaCal module.

Selecting the

NO soft key will temporarily

transfer only the portion of the characteriza

-

tion data necessary for this particular calibra

-

tion. This transfer takes aproximately 30 to 60

seconds, and will have to be repeated every

time a calibration is done using this combina

-

tion of Site Master and InstaCal module.

6. Verify that the calibration has been prop

-

erly performed by checking that the

CAL

ON!

message is displayed in the upper

left corner of the display.

7. Remove the InstaCal module from the

RF Out port and connect the 20 dB Off

-

set to the RF Out port.

8. Measure the return loss of the 20 dB Off

-

set. The level should be 20 dB, ±2dB

across the calibrated frequency range.

9. Remove the 20 dB Offset from the RF

Out port and connect the 6 dB Offset to

the RF Out port.

10. Measure the return loss of the 6 dB Off

-

set. The level should be 6 dB, ±1.2 dB

across the calibrated frequency range.
