8201A Quick Start Guide

Version 1.00

( PN: 98407700A )

The 8201A is a versatile, precision, solid-state instrument with features and performance characteristics

suitable for laboratory and industrial applications. It covers a frequency range of 100 kHz to 2.5 GHz. The

8201A modulation analyzer is easy and convenient to use. This document brieﬂy describes the operat-

ing information for the Model 8201A Modulation Analyzer and all 8201A-S/### variants, including the

descriptions of the front and rear panel controls, displays, connectors, option selections, and instructions

for local and remote modes of operation. Typical measurement situations are also described. The 8201A

is an updated version of the discontinued Model 8201. The 8201A is fully compatible with the 8201 - the

two models have identical operation and speciﬁcations.

Getting familiar with Data Keypad

Operation of the data keypad is conventional. The data keypads of

the 8201A Modulation Analyzer are described as below:

Figure-5: Data Keypad of 8201A Modulation Analyzer

MHz key

Select the carrier FREQ function and depress the [8] key. The carrier

frequency display will indicate ‘8 and the unit’s legend will go out.

The tick mark (‘) indicates that the number displayed has not yet

been entered.

Continue by depressing the [2], [.], [1] and [5] keys and the MHz

key to enter the number. The display will now indicate 82.15000

MHz. (Note: It is not necessary to enter any trailing zeroes, nor is it

necessary to depress the ENTER key if a units key is used. While this

is the most efﬁcient way to enter 82.15 MHz, it is equally valid to

enter 82150 kHz, 82150000 Hz, etc).

DEL and CLR Key

If at any time before entry the wrong digit is entered, depress the

DEL key to clear the digit, or depress the CLR key to clear all input and

restore the previous frequency display.

Getting familiar with Function Keys

The function keys of 8201A modulation analyzer are described as

below:

The top row of illuminated switches are the function keys. These

keys are used to select the parameter to be displayed and to enable

the data keypad for subsequent data entry. The functions are carrier

FREQ, carrier LEVEL, audio SINAD, audio FREQ, audio DIST, AM, FM, PM,

SPCL, and PRGM. The LED in the switch of the selected function will

be illuminated continuously; the others will be off unless a measure-

ment of that function is in progress. In this case the LED will ﬂash

during the measurement interval.

FREQ function key

To select a function press the desired function key. The units legends

associated with that function will appear immediately to the right of

the numeric display.

For example, select the carrier FREQ function and press the 1 and V/

GHZ keys. The display will now contain the number 1000.0000 and

the active legend will be MHz

FM function key

Depress the FM function key. The LED in the carrier FREQ key will go

out, and the LED is the FM key will illuminate. Depress the 1, 0, and

kHz keys. The number 10.00 will now be displayed in the modulation

display.

All other function keys operate in the same manner, except that data

cannot be entered when the DIST or SINAD functions are selected.
