AVG
Press and release the SHIFT key, then the INCR x10 key to access the average
function. This enables or disables measurement averaging.
Programming AV G
The HP-IB command :AVERage is used to select this data function
programmatically.
NOTE:Measurement averaging works the same way programmatically as it does manually.
If the AVG data function is enabled manually and the number of aver ages is set to ten (N=10),
the first value displayed is the average of 1 measurement, the second value displayed is the
average of two measurements, the third value displayed is the average of three
measurements… the tenth value displayed is the average of 10 measurements. For readings
greater than N the data function approximates a hardware singl e -po le, RC low-pass filter.
If the AVG data function is enabled programmatically and the number of aver ages is set to ten
(N=10) the first value returned through HP-IB is the average of 1 measurement, the second
value returned through HP-IB is the average of two measurements, the third value returned
through HP-IB is the average of three measurements…the tenth value returned through HP-IB
is the average of 10 measurements. Each successive reading would mimic the output of a
single-pole, RC low-pass filter that had been initially charged to the value of the tenth reading.
If a “true average” value is desired, that is V
procedure through HP-IB is to take N sequential readings and calculate the average within the
program context.
To Turn Measurement Averaging ON and OFF.
= (V1+V2+V3…VN)/N, the recommended
avg
Use the :AVERage:STATe
commands to turn the averaging data function ON and OFF.
Syntax
:AVERage:STATe ON
:AVERage:STATe OFF
Example
OUTPUT 714;"MEAS:AFR:DISTN:AVER:STAT ON"
This turns the AVG data function ON for the AF Analyzer distortion
measurement.

Keys That Begin with the Letter A
To Query the Measurement Averaging State. Use the :AVERage:STAT?
commands to query the current state of the averaging data function. The returned
value is either: 0 (OFF) or 1 (ON).
Syntax
:AVERage:STAT?
Example
OUTPUT 714;"MEAS:AFR:DISTN:AVER:STAT?"
ENTER 714;State_on_off ! 1 = ON, 0 = OFF
This queries th e s ta te of t he AVG data function f or the AF Analyzer dist ort io n
measurement.
To Reset Averaging. Use the :AVERage:RESet commands to restart the
averaging algorithm used to calculate an averaged measurement.
Syntax
:AVERage:RESet
Example
OUTPUT 714;"MEAS:AFR:DISTN:AVER:RES"
This resets the AVG Data Function for the AF Analyzer distortion
measurement.
To Set the Number of Averages. Use the :AVERage:VALue commands to set the
number of averages used by the averaging algorithm.
Syntax
:AVERage:VALue
Example
OUTPUT 714;"MEAS:AFR:DISTN:AVER:VAL 25"
This sets the number of averages to 25 for the AVG data function for the AF
Analyzer distortion measurement.
To Query the Number of Averages. Use the :AVERage:VALue? commands to
query the number of averages used by the averaging algorithm.
Syntax
:AVERage:VALue?
Example
OUTPUT 714;"MEAS:AFR:DISTN:AVER:VAL?"
ENTER 714;Num_of_avgs
This queries the numbe r of averages for the AVG data function fo r the AF Analyze r
distortion measurement.

DATA FUNCTIONS Keys
The DATA FUNCTIONS keys can b e divide d into tw o groups; those which affect
measurements (REF SET, METER, AVG, HI LIMIT and LO LIMIT), and those
which affect numeric entr y fields (INCR
down-arrow). For measurements, the data functions enable the programmer to
change the way measurements are calculated and displayed, and provide
measurement limit detection. For numeric entry fields, the data functions enable
the programmer to set, scale, and change the field’s increment value.
Refer to the “Number Measurement Syntax” in the HP-IB Command Syntax
chapter of the HP 8924C Condensed Programming Reference Guide for full
command syntax.
Guidelines for Using Measurement Data Functions
•Data functions are turned ON and OFF for individual measurements. The HP-IB Data
Function commands must immediately follow the HP-IB command for the individual
measurement. For example, to turn the AVG data function ON for the AF Analyzer
distortion measurement, the following command string would be sent to the Test Set:
OUTPUT 714;"MEAS:AFR:DISTN:AVER:STAT ON"
•Attribute Units (AUNits) are used with the data function s to specify the units-of-
measure for numeric data which is read or set through HP-IB.
Refer to “To Specify Units-of-Measure for HP-IB Data Transfer” in
Overview
•Data function settings, such as number of averages or reference value, are retained if
the function is turned off. The setting values are initialized or changed under the
following conditio ns:
•The Test Set is turned off.
•The Test Set is PRESET.
•A saved register is recalled.

Guidelines for Using Numeric Entry Field Data Functions
•Increment values are set, scaled, and changed for individual numeric entry fields. The
HP-IB data function commands must immediately follow the HP-IB com mand for the
individual field. For example, to set the increment value for the RF Generator frequency
to 2.5 MHZ, the following command string would be sent to the Test Set:
OUTPUT 714;"RFG:FREQ:INCR 2.5 MHZ"
•HP-IB Units (UNITs) are used with the data functions to specify the units-of-measure
for numeric data which is read or set through HP-IB.
Refer to “To Specify Units-of-Measure for HP-IB Data Transfer” in
Overview
•Data function settings are not retained. The setting values are initialized or changed
under the following conditions :
•The Test Set is turned off (values initialized on power up).
•The Test Set is PRESET (values initialized).
•A saved register is recalled (values changed to those in the recalled register).

USER Keys
Chapter 1, Description of 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 used to mov e between se ttin gs on the screen th at is dis 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 gne d local user keys ar e available in each s cre en; 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.

Operating Considerations
•RJ-11(see figure 4 on page 84)
•The serial communications settings are defined on the I/O CONFIGURE screen.
•The IBASIC controller sends and receives data to the serial ports using address 9 for
the primary port (A), and address 10 for the secondary port (B). For example, to enter
data from the primary serial port (A) into a pro gram variable named SDATA, you could
use the command: ENTER 9;SDATA
•Using Port B: The secondary serial port (B) is only used with IBASIC programs to
communicate with other equipment when the primary serial port is used for printing or
data collection. Port B cannot be used for printing screens, and its communication
settings can only be changed using IBASIC commands.
Unless you are writing IBASIC programs that require serial printing and other serial
data transfer at the same time, we recommend that yo u only u se the primary serial po rt
(A).
•To send data from your program out of the primary serial port (A), you could use the
command: OUTPUT 9;SDATA
•Use an RJ-11/25-pin RS-232 adapter (HP P/N 98642-66508) and RJ-11cable
(HP P/N 98642-66505) to connect the Test Set to a serial printer or terminal/computer.
NOTE:RJ-11 Connectors: RJ-11 cables and adapters can be wired several ways by the cable
manufacturer. If you buy a cable or adapter other than the HP parts listed, verify the
connections for the pins indicated in table 3 on page 84 before connecting cables to the

Adjacent Channel Power Screen
How the Test Set Measures Adjacent Channel Power (ACP)
When you access t his scr een, th e Test Set automati cally st arts a multi- step proc ess
for measurin g ACP:
1. AF Generator 1 is turned off if the Carrier Ref field is set to Unmod.
2. The amplitude of the center frequency (Tune Freq) is measured to establish a refer-
ence.
3. AF Generator 1 is turned back on if it was previously turned off.
4. The power in each of the adjacent channels is analyzed.
5. Adjacent Channel Power is calculated and displayed. This value can be displayed as an
absolute power level or as a ratio referenced to the center frequency’s level.
NOTE:Which Input Port to Use. The TX Power measurement is used to calculate absolute Adjacent
Channel Power. Since TX Power can only be measured using the RF IN/OUT port, you must
use this port to measure ACP Level. ACP Ratio can be measured using either the RF IN/OUT
or the ANT IN port.
Measuring ACP on AM Transmitters. When measuring AM signals, the reference level
must be measured on an unmodulated carrier; so the Carrier Ref field must be set to
Unmod. After the reference is measured, th e power in the adjacent cha nnels must be measured
with modulation. This requires the modulating signal to be turned off and on repeatedly as
measurements are being calculated and displayed. Since the Test Set automatically turns
AFGen1 on and off when the Carrier Ref field is set to Unmod, you must use AFGen1
and the AUDIO OUT port as the modulation source for making AM ACP measurements.

Call Control Screens - CALL BIT
Figure 11 The CALL BIT Screen
The CALL BIT screen is designed to give an advanced user the capability to modify the
contents of the forward control channel and forward voice channel signaling messages
that are used in all processing messaging protocol.
A messaging protocol is defined as the sequence of messages sent from the Test
Set to the mobile station to perform a desired action, such as registering a mobile
station. Modifying the contents of one or more messages may be required for
testing the robustness of a mobile station’s call processing algorithms or for new
product development.
Using the CALL BIT Screen
Using the CALL BIT screen requires expert knowledge of the call processing
messaging protocol s used i n th e syst em selec ted in th e
System Type field on the
CALL CONTROL screen.
The CALL BIT screen should not be us ed to chang e any para meter th at can be s et
on any other Call Processing Subsystem screen. The contents of the applicable
fields on the CALL CONTROL screen and the CALL CONFIGURE screen are
not updated to refle ct any changes made whil e u sing the CALL BIT s creen. There
is no coupling between the CALL BIT screen and the Test Set.
For example: changing the valu e of the SAT color code fie ld (SCC) i n the for ward
control channel mobile st at ion control message (MS Int VCh) does not change the
setting of the
SAT: field on the CALL CONTROL screen.

When using the CALL BIT screen the user is responsible for setting the contents
of all messages used in a messaging protocol. When using the CALL BIT screen,
the Call Processing Subsystem sends the correct messages at the correct times as
defined in the applicable industry standard. Message content is the responsibility
of the user.
When the CALL BIT screen is displayed and the Call Processing Subsystem is in
the connected state, the Test Set constantly monitors the station’s transmitted
carrier power. If the Power falls below 0.0005 Watts, the error message
Power Loss indicates loss of Voice Channel
will be displayed and the

Test Set will terminate the call and return to the active state.
NOTE:In order to ensure that the Test Set makes the correct decisions regarding the presence of the
mobile stations’s RF carrier, the Test Set’s RF power meter should be zeroed before using the
Call Processing Subsystem. Failure to zero the power meter can result in erroneous RF power
measurements.
