1 Safety Information This instrument is Safety Class III according to IEC classification and has been designed to meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use). This instrument has been tested in accordance with EN61010-1 and has been supplied in a safe condition.
2 General Information 2.1 About this Guide This guide is comprised of the on-screen Help instructions available on the instrument itself, plus some essential extra information, e.g. Safety. The on-screen Help is split into Topics associated with each sub-menu of the five top-level menu groups; each Topic explains the functions accessible via that sub-menu, see section 3.8.2 for details.
2.3 Items Supplied Portable Spectrum Analyzer with detachable bench-stand/screen protector AC power-supply/charger universal voltage, interchangeable plugs for different countries. Spare stylus USB lead - mini B plug to standard A plug. Trigger input converter plug - 3.5mm jack to BNC. Short Guide Multi-language (English, French, German, Italian and Spanish). Full instruction manual (English only). Support CD containing hyper-linked PDF versions of the printed manuals plus support files. 2.
USB Host Connector type A connector on the left side revealed by moving the sliding cover. This is exclusively for the connection of a USB Flash memory drive used for file transfer. USB Device Connector type Mini B connector on the left side revealed by the sliding cover. This is intended exclusively for connection to a personal computer - see File Ops > Link to PC. Trigger Input/Output 3.5mm mono jack socket. Only functional when option U01 is fitted. 2.
3 Quick Start Guide It is recommended that all users, including those fully familiar with RF spectrum analyzers, take a little time to read through this instruction manual before using the instrument. However, for users who wish to get started with hands-on operation as quickly as possible, the following may prove useful. 1. Press and hold the Power key until the screen backlight flashes. Wait a few seconds and then check the battery condition indicator on the display.
4 Menu System 4.1 Control via the Menu System The default menu system for the instrument consists of three rows of five keys. The upper row represents the top level of the menu system and defines five menu groups as follows: Freq/Span controls the frequency range of the spectrum analyzer, as well as Zero Span mode. Sweep/BW controls the sweep and sets the RBW. Level/Limits controls the input attenuator, plus the scaling of the amplitude display. Limits is only available with option U01 fitted.
Set C=M1 Set C=Pk Step Down Step Up C=M1 sets the centre frequency to the Marker 1 frequency. C=Pk sets the centre frequency to the frequency of the peak amplitude within the current span. Step Up/Down changes the centre frequency by the step value as set by the Step Size function from the Frequency/Span menu. 4.3.2 Frequency/Span > Span Span Pressing Span changes the top line annotation to Centre/Span if it was previously Start/Stop.
Undo < Undo reverts to the start and stop frequencies that existed directly before the Start=M1/Stop=M2 key was pressed. -more1 of 2 More 1 of 2 selects a further set of function keys that provide an additional method for changing the start and/or stop frequencies based upon the frequency step size: Fix Start fixes the start frequency at its present value so that the Step Up/Down keys operate only on the stop frequency. The word Fix appears against the start frequency at the top of the screen.
4.4 Sweep/BW 4.4.1 Sweep/BW > RBW RBW Auto Enables the Resolution Bandwidth (RBW) for the sweep to be set: Auto automatically selects an appropriate RBW for the current span. When selected, the word Auto appears in front of the RBW value. 15kHz fixes the RBW at 15kHz providing the highest resolution and lowest noise, but increasing sweep time for wider spans. 280kHz fixes the RBW at 280kHz providing a compromise between sweep speed and resolution.
4.5 Level/Limits 4.5.1 Level/Limits > Units/Graticule Enables the level to be shown in either dBm or in dB microvolts. It also enables the Units/ Graticule brightness of the graticule to be controlled. dBm dBuV dBm selects level measurement in dBm (decibels relative to 1mW into 50 Ohms). dBuV selects level measurement in dB micro volts. Note that the measurement unit applies to both the graticule values and to the marker level readout.
On and Off turns the currently selected offset or compensation on or off. Set Offset opens a numeric or Tab/Jog screen from which the fixed offset can be set. Select Table opens a file recall screen for compensation tables created in PSA-Manager. 4.5.6 Level/Limits > Limits Limit lines, limit patterns and limits comparison functions are only available when Option U01 is installed. Limits can be simple straight lines or complex patterns of level against frequency.
Peak Hold Average Reset More Peak Hold the trace is written with the highest amplitude obtained from the current sweep. Average the trace is written with the highest amplitude obtained from the current sweeps. Reset operates in both Average and Peak hold modes to re-start the process from zero.
Trace & State recalls the stored trace to the Reference trace and changes the set-up state. Screen Image replaces the upper section of the screen with the stored image. Recall File brings up a file window from which the chosen file can be selected and recalled. Files are listed by date. ‘Find A-Z’ lists only files starting with that character. ‘Latest Files’ lists up to 20 recently stored or recalled files.
4.7 Setup/Functions 4.7.1 Setup/Functions > Logging Logging Log Type Logging functions are only available when Option U01 is installed. Log Type creates a pop-up menu that selects the type of data to be logged. Options are Centre Level, Peak Level, Full Trace, or Screen Image. Log Trigger creates a pop-up menu that selects the trigger for logging entries. Options are Timer, Manual (using Run/Stop key), External trigger input (+ve or -ve level change), Limits Event or Continuous (log after every sweep).
4.7.3 Setup/Functions > System/File-Ops System/ File Ops Provides access to the instrument system settings and to various filing system operations including connecting an external drive or PC. System Utilities System Utilities operates as a shortcut to the System Utilities menu. See section 2.8.1. File Ops the File Operations screen is an extended version of the File Utilities screen provided for Store and Recall.
System Update has the following functions: Calibrate Hardware provides the capability for recalibration of the spectrum analyzer hardware. Note that re-calibration requires the product service manual and precision RF equipment. Install Options allows Option U01 to be installed. Update Firmware enables updating of the instrument firmware. Note that updating of firmware or installation of options requires a USB Flash drive. 4.8.
5 Maintenance | Updates | Further Information 5.1 Recalibration & Repair To ensure that the accuracy of the instrument remains within specification, the calibration should be checked (and if necessary adjusted) annually. TTi or their agents overseas will provide a calibration service for any PSA1302/2702 and will repair any PSA developing a fault.
