Specification
Specifications apply at 18º - 28º after one hour warm-up, at maximum output into 50
Ω
.
FREQUENCY
Frequency Range:
0·005Hz to 5MHz in 7 overlapping decade ranges with adjustment by
coarse and fine verniers.
Vernier Range:
1000:1 on each range.
Frequency Display:
Auto-ranging reciprocal measurement giving 4-digit resolution down to
10Hz (to 1Hz on the 5Hz range); resolution is fixed at 0·01Hz below 10Hz
(0·001Hz below 1Hz on the 5Hz range).
Accuracy is ± 1 digit 5MHz to 2·1Hz (to 0·21Hz, Symmetry off, or to
0·42Hz, Symmetry on, on the 5Hz range); below this the accuracy is ± 1%
of range full scale (unspecified with Symmetry on).
Frequency Locking:
With vernier setting between 10% and 100% of range maximum,
frequency can be locked to the crystal reference to maintain it at the
displayed value ± 0·01%.
WAVEFORMS
Waveform specifications apply for the top decade of each frequency range.
SINE
Distortion:
Less than 0·5% on 500Hz, 5kHz and 50kHz ranges; less than 1% on 5Hz,
50Hz and 500kHz ranges; all harmonics >25dB below fundamental on
5MHz range.
Amplitude Flatness:
± 0·2dB to 200kHz; ± 2dB to 5MHz.
TRIANGLE
Linearity:
Better than 99% to 200kHz.
SQUAREWAVE
Rise and Fall Times:
<45ns.
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: 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.
