FREQ. 1 to the FREQ. 2, duration is defined in the TIME field.
3.
MODE
•
SINGLE/CONTINUOUS.
If CONTINUOUS, generator generates output signal until stopped manually. If SINGLE, generator
generates output only for time specified in the TIME field, then stops automatically.
4. TIME
•
Specifies duration of the output signal generation for the single shot mode, and specifies the ramp
time/repetition rate of sweeps. Range: 10 – 9900ms, Step: 10/100ms.
5.
SCALE
•
Sets LINEAR or LOGARITHMIC response characteristic for sweeps.
6.
FREQ. 1
•
Specifies frequency for the first tone or starting frequency for the frequency sweep.
Range: 150Hz – 9999Hz, Step: 1Hz.
7.
FREQ. 2
•
Specifies frequency for the second tone or final frequency for the frequency sweep.
Range: 150Hz – 9999Hz, Step: 1Hz.
8.
LEVEL 1
•
Specifies amplitude for the first tone or starting signal level for the amplitude sweep.
Range: 1μV – 130mVp-p, Step: 1
9.
LEVEL 2
•
Specifies amplitude for the second tone or final signal level for the amplitude sweep.
Range: 1μV – 130mVp-p, Step: 1
10.
MONITOR
•
Enables and sets monitoring level of signal generator output through internal speaker.
Please note, if you do require extreme output signal purity, keep it OFF.
CONNECTING TONE OUTPUT TO THE TRANSCEIVER
Tone generator output is located at the rear panel, at the TEST TONE jack. Its output is designed to be directly
connected to the microphone jack of all common transceivers, however, user is supposed to build own cable
according to following instructions. Jack is 3.5mm, 4 pole type. Audio uses two poles for microphone signal and
microphone ground. PTT uses another two poles for PTT and PTT ground. PTT ground is internally connected to
the system ground of the meter, audio ground is isolated. Use shielded cable and chart below, shield has to be
used for PTT ground (PTT GND).
