Getting Started

This chapter will help familiarize you with fundamental Test Set operation, including:

• Accessing screens and fields

• Making a simple measurement

• Preparation for remote operation via GP-IB

Chapter 1, Getting Started

Before Connecting a Radio

NOTE: The RF IN/OUT port should be used for all transmitter tests when th e radio is connected

directly to the Test Set. (All MSUT (Mobile Station Under Test) transmitter power measurements are made through this port). Off-the-air measurements can be made using the highly-sensitive ANT IN port.

CAUTION: Overpower Damage — Refer to the Test Set’s front panel for maximum input power level.

Exceeding this level can cause permanent instrument damage.

Other Damage — Blocking the fans’s rotation or operating the Test Set in an environment that causes excessive heat may cause damage.

Important: If excessive temperatures are sensed on the power supply regulator assembly, the Test Set’s power supply will shut off. After temperature has lowered to within normal operating range, use the POWER switch to cycle power on. Remove RF power from the RF IN/OUT connector whenever the Test Set is off.

Accessing the Test Set’s Screens

CDMA and Analog Modes

The Test Set has two operating modes, analog and CDMA. In CDMA mode, the T est Set conf igure s itself as a cal ibrat ed CDMA base st ation . In Ana log mode, t he Test Set has AMPS, NAMPS and TACS analog cellular phone test capability.

CDMA is the default power-up mode. To enter analog mode from CDMA mode:

• press one of the ANLG SCRNS keys, or

This procedure will clear all SAVE registers, including POWERON.

Chapter 3, Operating Overview

Saving and Recalling Instrument Setups

To Specify a BASE Setting

The BASE register contains any field settings the user has SAVEd that are different fro m the instrume nt PRESET state. I t establish es a refere nce point fo r all future SAVEs. (The PRESET state is stored in the BASE register until you SAVE another instrument setup.)

When you SAVE an instrument setup, the new setup is compared to the BASE settings, and any differences are stored under the register name you supply. Because only differences are stored, a much larger number of instrument setups can be saved than if the contents of every field was saved.

When you RECALL an instrument setting, every field is reset to the BASE settings. Th e SAVED set tings are then u sed to re-establish the desired instrument setup.

You can define your own BASE setting. If your d esi red settings are very different from the PRESET values, you may want to change the BASE register. This will decrease the amount o f memory used to SAVE e ach setup , and all ow you to SAVE many more setups.

CAUTION: Since each SAVE/RECALL register only contains the differences between the setup being

saved and the presen t BAS E regist er sett ings, ch anging the BASE res ults in all ot her sav ed setups being ERASED from memory (including the POWERON setting if one has been saved).

Unless you consistently change the same fields to the same value each time you use the instrument, you should probably not create your own BASE settings.

Memory Considerations

When the Save/Recall field of the I/O CONFIGURE screen is set to

Internal, instrument setups are saved to the same non-volatile RAM used to

create RAM Disk(s) and run IBASIC programs. By saving a large number of instrument setups, you reduce the amount of RAM available to run programs. If

you get a “memory overflow” message while trying to load a program, you must clear one or more SAVE/RECALL registers to free RAM space).

Using USER Keys

User keys instantly access instrument settings without using the knob. You can use USER keys to move quickly between fields on the same scree n, and to ac ces s field settings that are not normally available on the screen you are using.

Local USER keys are used to move between settings on the screen that is displayed. When the USER key is pressed, the cursor instantly moves to, and selects, the assigned field; eliminating the need to turn and push the knob. Five local USER keys are available for each screen: K1, K2, K3, K4, and K5.

Global USER keys are used to acce ss se ttin gs that ar e not ava ilabl e on th e curre nt

screen. Three global USER keys are available: K1’, K2’, and K3’. (These are shifted functions of the local USER keys.)

USER Keys

User keys instantly access instrument settings without using the knob. You can use user keys to move quickly between fields on the same screen, and to access field settings that are not normally available on the screen you are using.

Local user keys are u sed t o move between setting s on the screen that i s d is played. When the user key is pressed, the cursor instantly moves to, and selects, the assigned field; eliminating the need to turn and push the knob. Five local user keys are available for each screen: k1, k2, k3, k4, and k5.

Five factory-assi gned local user keys are av ail ab le in eac h screen; however, using these keys removes any other local user keys you may have already set up.

Global user keys are used to access settings that are not available on the current screen. Three global user keys are available: k1’, k2’, and k3’. (These are shifted functions of the local user keys.)

When defining user keys, the ASSIGN function is used to create key definitions; the RELEASE function removes the definitions. Re-assigning a user key to a different field setting automatically releases it from the setting it was previously associated with.
