ADRS

Press and release the SHIFT key, then the LOCAL key to display the HP-IB address of the Test Set. The re is no equi valent HP- IB command for the ADRS key
Programming AD RS
The Test Set’s HP-IB address can be changed through HP-IB by using the :CONFigure:BADDress commands. If the Test Set’s HP-IB address is changed programmatically, all future HP-IB commands must use the new address.
Example
OUTPUT 714;"CONF:BADD 15"
This sets the Test Set’s HP-IB address to 15.
Chapter 1, Description of Keys
Keys That Begin with the Letter A
ANS
The Test Set’s HP-IB address can be queried through HP-IB by using the :CONFigure:BADDress? commands.
Example
OUTPUT 714;"CONF:BADD?" ENTER 714;Address
This queries the Test Set’s HP-IB address.

Chapter 1, Description of Keys Keys That Begin with the Letter A
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.

S:\hp8924c\REFGUIDE\MANUAL\keys.chp
Chapter 1, Description of Keys
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 :

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.

ANTENNA IN

The antenna input is used to analyze low-power RF signals ( 200 mW), and is typically used for off-the-air measurements. This port can be selected in the analog TX TEST, DUPLEX TEST, RF ANALYZER, or SPECTRUM ANALYZER screens.
Operating Considerations
•BNC
Input impedance = 50
TX Power cannot be measured using this port; use the RF IN/OUT port. However, low power levels can be measured using this port with the spectrum analyzer.
Additional sensitivity for this port is available using the Sensitivity field in the analog RF ANALYZER and SPECTRUM ANALYZER screens.
Chapter 2, Description of Connectors
Connectors That Begin with the Letter A
CAUTION: Connecting a signal of >200 mW to the ANT IN port can cause instrument damage (although
internal protection circuits can typically withstand a short-duration signal of 1 or 2 Watts).
If the over-power circuit is triggered (signified by a warning message at the top of the screen), remove the signal from the ANT IN port, and press the MEAS RESET key, or turn the Test Set off and on to reset it.

AUDIO IN LO, HI

The audio inputs are used to input audio signals to the AF Analyzer.
AUDIO IN HI is the main audio signal input connection.
AUDIO IN LO is used for the audio signal reference. Three choices are available using the AF ANALYZER screen's Audio In Lo field:
Gnd - connects the center pin through approximately 100 to chassis ground
Float - provides a floating input.
600 To Hi - provides a 600 internal load to match an audio source with an output.
The measured level is the po tenti al bet ween the HI and LO cente r pins . The shell s of both connectors are at chassis ground.
Operating Considerations
•BNC
Input impedance switchable between
•1 MΩ in parallel with 95 pF,
•600Ω floating.
This port is selected as the AF Analyzer's input using the AF Anl In field in the analog TX TEST screen, DUPLEX TEST screen, and AF ANALYZER screen. This port is always the AF Analyzer's input when the analog RX TEST screen is displayed.
Signals input to the AF Analyzer are routed through different filters, amp lifiers , and detectors that affect the displayed measurement.
CAUTION: The maximum level between the HI and LO center pi ns is 42 V pe ak (appr oximate ly 30 Vrms).
Exceeding this value can cause permanent instrument damage.

SERIAL PORT

This connector is used for serial control of an HP 83236 PCS Interface, or for serial data exchange with some other device. A serial cable is provided with the HP 83236 to connect the SERIAL PORT to a DB-15 connector on the HP 83236. Other applications for the SERIAL PORT might include; entering IBASIC programs, printing tes ts res ults and scre en images , or send ing te st res ults f rom the IBASIC controller to a connected controller, disk drive, or terminal.
If you are using this connector to enter programs, or you would like to see a diagram of the connectors and pin-outs to the serial port, refer to

chapter of the HP 8924C Application Guide.
Chapter 2, Description of Connectors
Connectors That Begin with the Letter S
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 instruments.
Table 3 on page 84 lists connections for the primary serial port (address 9). Wh en using both ports at the same time, you need to locate or fabricate an adapter to provide the necessary connections.

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.

Figure 9 The ANALOG MEAS Screen
This screen is used to make RF and audio measurements on the mobile station connected to the Test Set while on an active voice channel.
The Test Set does not monitor the mobile stat ion’s transm itted carrier power while the ANALOG MEAS screen is displayed. If the power falls below 0.0005 Watts no error message is displayed nor will th e Test Set terminate the call while on the ANALOG MEAS screen.
Requirements for Using The ANALOG MEAS Screen
The Test Set must be in the connected state (that is, the Connect annunciator is lit) in order to use the ANALOG MEAS screen.
The mobile station’s speaker output must be connected to the Test Set’s AUDIO IN connector and the mobil e st at io n’s micr ophon e in put must be conne ct ed to the Test Set’s AUDIO OUT connect or in order to use t he ANALOG MEAS screen. If the mobile station does not have audio connections the ANALOG MEAS screen cannot be used.

How To Program The ANALOG MEAS Screen
The ANALOG MEAS screen combines some of the Tes t Set’s Audio Analyzer fields and some of the Test Set’s
RF Generator fields onto one screen for the
purpose of testing the audio characteristics of the mobile station. Only those fields which are pertinent to testing the mobile station’s audio
characteristics have been combined onto the

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.

Chapter 3, Description of Screens
Call Control Screens
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

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.
