GENERAL INFORMATION
1-4
Non-volatile memory
The non-volatile memory allows 50 complete instrument settings, 50 partial settings, 100
carrier frequency settings, 20 sweep settings and 20 signalling tone sequences to be stored for
later use at any time.
Programming
A GPIB interface is fitted so that all functions are controllable via the interface bus which
is designed to the IEEE Standard 488.2. The instrument can function both as a talker and a
listener.
Software protection
To prevent accidental interference with the contents of internal memories, internal data is
protected by a secure key sequence.
Two levels of protection are offered, appropriate to the function being accessed. The
most secure is reserved for features which alter the calibration data of the instrument.
Spectral purity
With an SSB phase noise performance of typically -122 dBc/Hz at 470 MHz (20 kHz
offset), the 2030 Series can be used for both in-channel and adjacent channel receiver
measurements. Harmonically related signals and non-harmonics are better than -30 dBc and
-70 dBc respectively.
Calibration
The 2030 Series has a recommended two year calibration interval and is calibrated
entirely by electronically controlled adjustment. There are no internal mechanically adjustable
components to affect the calibration. The calibration display is available via soft key selection at
the utilities menu.
Date stamping
After readjustm
ent the instrument updates the calibration data and records the date of
adjustment. The calibration due date can be set and when this date is reached a message advises
the operator to return the unit for calibration.
Options
The following factory-fitted options are available:
Option 001 - Second modulation oscillator
An additional modulation oscillator is available to enable greater flexibility. This second
oscillator has the same specification as the first and allows full use of complex modulation
modes.
Option 002 - Pulse modulation
The pulse m
odulation facility allows radar RF and IF stages to be tested and features rise
and fall times of less than 15 ns with an on/off ratio of better than 70 dB.
Option 003 - High output power
This option extends the output level to +19 dBm
on the 2030 model.
