Making a Measurement

This instrument enables you to make a wide variety of measurements on digital communications equipment using the measurement capabilities. It also has optional measurement personalites that make measurements based on industry standards.

To set up the instrument to make measurements, you need to:

1. Select a mode or personality which corresponds to a digital communications format, like cdma2000, W-CDMA, or EDGE. Use the Basic mode to make measurements of signals with non-standard formats. After selection of the mode, adjustments to the mode settings may be made as required.

2. Select a specific measurement to be performed, like ACP, Channel Power, or EVM, etc. After selection of a measurement, adjustments to the measurement settings may be made as required.

Basic Mode

Depending on Measurement Control settings, the instrument will begin making the selected measurements. The resulting data will be shown on the display or available for export.

3. Select a front panel View to display the data from the current measurement. Depending on the mode and measurement selected, various graphical and tabular presentations are available.

If you have a problem, and get an error message, see the E4406A VSA Transmitter Tester Instrument Messages and Functional Tests Guide.

The main keys used in the three steps are shown in the table below.

Getting Started Front Panel Description

Front Panel Description

Key menus may vary depending on the currently selected mode or measurement. Softkeys which are not available for use are greyed-out. Keys may be greyed-out as a result of:

the current setting of other inter-related functions, not having a required password or license key, or not having some piece of optional hardware that is required.

Paths to access any feature will be found in the key access table on

page 53. Display annotation is explained on page 33. Operation of the

3.5 inch floppy-drive is covered in the section on printing on page 63.

1. ESC key Use the escape key to exit any function without modifying current parameters. Pressing the

ESC key

will:

• Clear any numeric entry that you have begun to

enter but decided you want to cancel.

• Remove any entries that are visible in the active

function area of the display (see the section on annotation on page 33 for a description of the active function area and other display features).

• Cancels an alignment if one is in progress.

2. Control keys Sets parameters that are used by the measurement in the current measurement mode.

9. Probe Power The probe power input supplies power for external probes; the three connectors are a ground, and a +15 V, and a

−12.6 V connector. The probe power supplies

power to high frequency probes and accessories, such as preamplifiers, that are used as accessories to the transmitter tester. The probe power provides a maximum of 150 mA.

10. RF Input The 50

Ω RF input allows for input of an external RF

signal. The connector is a type N female, and is rated for a maximum input of +35 dBm for measuring a CW signal, and a maximum of 26 volts for a DC signal.

11. Data Entry keys are used to enter numeric values. Entries made using data entry keys will be visible in the active function area (see the section on annotation on page 33 to locate the active function area).

• The

Enter key is used to terminate numeric data

where no units of measurement are being entered, or where you want to terminate with the default unit of measurement. For operations involving selection of a unit of measurement (for example, dB, dBm, Hz, s, degrees, radians), the

Units softkey menu

(explained below) is used to terminate numeric entries.

Units softkeys are used to enter units of

•

measurement. If the value you are entering is in units of measurement, the units softkey menu will automatically appear once you enter a digit. After entering the desired numeric value, you terminate the entry by pressing the appropriate units of measurement softkey.

Numeric keys enter numeric values as indicated on

•

the keys. In addition, decimal and positive and negative sign keys are available for your use.

• The

Step keys (these are the up and down arrow

keys) change numeric values in increments of the current step size.

• The

Backspace key moves the cursor backwards one

space and erases the character in that space. You can use the

Backspace key to backspace characters in

the active function area.

• The RPG Knob changes numeric values in

increments of the current knob resolution.
