Specification
Specifications apply at 18º - 28º after one hour warm-up, at maximum output into 50
Ω
.
FREQUENCY
Frequency Range:
0·03Hz to 3MHz in 7 overlapping decade ranges with adjustment by vernier
control.
Vernier Accuracy:
(TG310 only)
Typically ± 5% of full scale.
Vernier Range:
1000:1 on each range.
Frequency Display:
(not TG310)
Auto-ranging reciprocal measurement giving 4-digit resolution down to 10Hz
(to 1Hz on the 3Hz range); resolution is fixed at 0·01Hz below 10Hz
(0·001Hz below 1Hz on the 3Hz range).
Accuracy is ±1 digit to 2·1Hz (to 0·21Hz, Symmetry off, or to 0·42Hz,
Symmetry on, on the 3Hz range); below this the accuracy is ± 1% of range
full scale (unspecified with Symmetry on).
WAVEFORMS
Waveform specifications apply for the top decade of each frequency range.
SINE
Distortion:
Less than 0·5% on 300Hz, 3kHz and 30kHz ranges; less than 1% on 3Hz,
30Hz and 300kHz ranges; all harmonics >25dB below fundamental on
3MHz range.
Amplitude Flatness:
± 0·2dB to 200kHz; ± 2dB to 3MHz.
TRIANGLE
Linearity:
Better than 99% to 200kHz.
SQUAREWAVE
Rise and Fall Times: <100ns
Mark-Space Ratio:
1:1 ±1% to 100kHz
DC
Range:
±10V (unterminated).
SYMMETRY
Symmetry Range:
Variable typically between 1:9 and 9:1 (on top decade of each range),
frequency divided by 10 when Symmetry is selected.
MODULATION MODES
Modulation can be used with all waveforms and at any frequency.
Sweep
Sweep Mode:
Internal (TG330 only):
linear or logarithmic; sweep Start and Stop
frequencies displayed at a press of a button.
External:
linear.
Sweep Width:
Up to 1000:1 within each range.
Sweep Rate:
Internal sweep rate adjustable from typically 20ms to 20s.
External Sweep:
By signal applied by SWEEP IN/OUT socket.
