Agilent 89410A Data Sheet

Introduction
Specifications describe warranted performance over the temperature range of 0° to 45°C (except where noted) and include a 30-minute warm-up from ambient condi­tions, automatic calibrations enabled, auto-zero on, time domain calibration off, and anti-alias filter in, unless noted otherwise. Supplemental characteristics identified as “typical” or “characteristic,” provide useful informa­tion by giving non-warranted performance parameters. Typical performance is applicable from 20° to 30°C. When enabled, automatic calibrations are periodically performed to compensate for the effects of temperature and time sensitivities. During the calibration, no signals > 0 dBm should be connected to the front panel inputs.

See time specifications for main time length and time resolution details.

FSK error
Magnitude error Carrier offset frequency Deviation
Detected bits (symbol table)
Binary bits are displayed and grouped by symbols. Multiple pages can be scrolled for viewing large data blocks. Symbol marker (current symbol shown as inverse video) is coupled to measurement trace displays to identify states with corresponding bits. For formats other than FSK and MSK, bits are user-definable for absolute states or differential transitions. Note: Synchronization words are required to resolve carrier phase ambiguity on non-differential modula­tion formats.
Accuracy (formats other than FSK and IS-95 CDMA)

Adaptive equalization
This option equalizes the digitally-modulated signal to
remove effects of linear distortion (such as unflatness
and group delay) in a modulation quality measurement.
Equalizer performance is a function of the filter design (e.g., length, convergence, taps/symbol) and the quality of the signal being equalized.

Digital video modulation analysis— Option 89410A-AYH (requires Option 89410A-AYA)
This option extends the capabilities of the vector modulation analysis Option 89410A-AYA by adding modulation formats used for digital video transmission. Except where noted, all of the standard capabilities of Option 89410A-AYA are provided for the new modula­tion formats.

Maximum symbol rate
Option 89410A-AYH analyzes vector modulated signals up to a maximum symbol rate determined by the infor­mation bandwidth of the receiver mode and the excess bandwidth factor (a) of the input signal, according to:
Max symbol rate
Information bandwidth
1 + a
(Note: the maximum symbol rate is doubled for VSB signals.)
Receiver mode Information bandwidth
ch1 + j*ch2 20 MHz
1
0 to 10 MHz 10 MHz External 10 MHz
1
Example: For a 64QAM signal (a = 0.2), the maximum symbol rate in 0-10 MHz mode is 10 MHz/(1.2) = 8.33 Msymbols/second.
Measurement results and display formats
Identical to Option 89410A-AYA measurement results and display formats except for the following changes to the error summary display:
VSB pilot level is shown, in dB relative to nominal.
For VSB formats, SNR is calculated only from the real part of the error vector.
For DVB formats, EVM is calculated without removing IQ offset.

Trace select
When a waterfall or spectrogram measurement is paused or completed, any trace in the trace buffer can be selected by trace number or by z-axis value. The marker values and marker functions apply to the selected trace.
Z-axis value
The z-axis value is the time the trace data was acquired relative to the start of the measurement. The z-axis value of the selected trace is displayed as part of the marker readout.
Display update rate 30 to 60/second, typical
Memory required (characteristic only)
Displays occupy memory at the rate of 175 traces/ Mbyte (for traces of 401 frequency points). A full screen of 307 traces will require 2.25 Mbytes of free memory.
