Digital signal generator claims price breakthrough
Signal Forge has released the first high-performance digitally synthesised signal generator with an 800MHz range, usable to 1GHz, for under $1000.
An alternative approach to bit error rate testing
Steven Robalino discusses a test methodology that may be applied to a wide range of datacommunications systems and devices which transmit data over a serial bus.
The new release provides enhanced waveform functions including chirp, pulsed chirp (pulsed FM) and BPSK.
The new waveforms add test capabilities needed by developers of wireless devices such as GSM, RFID, wireless LAN, and Zigbee.
Test methodologies supported by the new software include receiver blocking tests and interfering frequency tests.

Modules expand range of signal generator
Addon modules for the SF1000 signal generator allow the user to add higher RF frequency capabilities without buying an entirely new signal generator.
The BPSK waveform operates with a carrier frequency between 1Hz and 100MHz.
It can be modulated internally using a Wave Manager menu selection or via an external controller.
BPSK is a form of PSK which uses two phases separated by 180 degrees and is sometimes called 2-PSK.
It modulates at 1bit/symbol and is used for testing low data-rate applications such as IEEE802.11g wireless LAN standard.
bit/sK is also suitable for testing low-cost passive transmitters such as those used in the RFID standards which have been adopted for biometric passports, credit cards and other applications.
ZigBee devices which operate in the 868-915MHz frequency band also employ bit/sK.
The chirp waveform, which is used to test a variety of communications and radar systems, repeatedly ramps the output between two user-selected frequencies over a specified time.
The user simply specifies the chirp duration and the Signal Forge generator automatically calculates the delta frequency and ramp rate for the chirp.
When using chirp at a frequency of 100MHz or less, the SF1000 provides an option to idle at 0Hz instead of the starting frequency.
The pulsed chirp waveform ramps the output from a user-selected frequency 1 to frequency 2, jumps back to the starting frequency, and then idles there until the next chirp (the nonpulsed chirp waveform immediately begins the next chirp).
Both the chirp and pulsed chirp waveforms operate from 1Hz to 1GHz with a frequency step rate of up to 50kHz.
Both waveforms may be used with the Signal Forge generator's AC-coupled, digital and differential outputs.
Wave Manager release 5 is now shipping with all SF1000 signal generators.
Previously shipped SF1000 or SF800 signal generators may be updated with the new release by downloading the Wave Manager release 5 from the Signal Forge website.
