TTI TG320 函数发生器 (3MHz, đếm tần số ngoài)

FREQUENCY
Frequency Range: 0.03Hz to 3MHz in 7 overlapping decade
ranges with fine adjustment by a vernier.
Vernier Range: 1000:1 on each range.
OPERATING MODES
Specifications apply for the top decade of each frequency range and maximum output
into 50 termination.
SINE
Distortion: <0.5% on 300, 3k and 30k ranges; <1% on
3, 30 and 300k ranges; all harmonics >25dB
below fundamental on 3M range.
Amplitude Flatness: ±0.2dB to 200kHz; ±2dB to 3MHz.
TRIANGLE
Linearity: Better than 99% to 200kHz
SQUARE WAVE
Rise/Fall Times: <100ns
Mark - Space Ratio: 1:1 ± 1% to 100kHz
DC
Range: ±10V unterminated
SYMMETRY
Symmetry Range: Variable typically 1:9 to 9:1 (on top decade of
each range), frequency divided by 10.
METER FUNCTIONS (generator mode)
Frequency: Auto-ranging reciprocal measurement giving
4 digit resolution for frequencies down to
1Hz; maximum resolution is 0.001Hz.
Accuracy ±1 digit for 0.2Hz to 3MHz.
Below 0.2Hz accuracy is ±1% of range full
scale (symmetry off).
Amplitude: Display shows peak-to-peak amplitude or rms
value. Display corrected for attenuator setting.
3-digit resolution, accuracy typically 5%
of range. Clipping indicator on display.
DC Offset: 3-digit resolution; accuracy typically ±2% of
setting ±1 digit. Display corrected for attenuator
setting. Clipping indicator on display.
OUTPUTS
MAIN - 50 Ohm
Amplitide 2mV to 20V peak-peak open circuit (1mV to
10V peak-peak into 50) in four switchselectable
ranges with 20dB vernier control
within each range
Attenuator Ranges: 0dB, -20dB, -40dB, -60dB
DC Offset Range: ±10V from 50. DC offset plus signal peak
limited to ±10V (±5V into 50). DC offset
plus waveform attenuated proportionally by
the attenuator.
MAIN - 600 Ohm Alternative output socket offering the same
facilities as the 50 socket.
AUX OUT 0 to 5V TTL/CMOS logic levels capable of
driving 2 standard TTL loads. Frequency,
symmetry and phase as main outputs
SWEEP OUT 3V ramp from 600 (TG330 only)
